ISC 2026 - Day 2

<h4>What if you could compress 179 days of grueling laboratory workflow into just 14 hours?</h4>In this episode of ‪ChromatographyTalk‬, ‪Organomation‬ General Manager David Oliva sits down with analytical chemist Laura Penabad to discuss her groundbreaking new research in biocatalysis and high-throughput screening. Evolving engineered enzymes typically requires checking thousands of variants—a massive bottleneck when traditional Liquid Chromatography-Mass Spectrometry (LC-MS) runs take minutes per sample. Laura reveals how her team built a modular screening platform that shatters this limitation, running samples 128 times faster than standard methods without sacrificing analytical accuracy.Laura breaks down the "orchestra" of technologies making this possible, including coupling nanoliter droplet microfluidics with Cyclic Ion Mobility-Mass Spectrometry (cIM-MS) to separate complex chemical isomers in milliseconds. She also shares the chaotic but triumphant behind-the-scenes stories of her PhD journey—from presenting a "comically bad" early poster at ASMS to recruiting an undergraduate mechanical engineer to build custom automation software from scratch.If you are an early-career researcher, a mass spec enthusiast, or curious about the future of synthetic biology and machine learning in chemistry, this episode is packed with invaluable intuition and advice.<h3>Video Transcription</h3><h4>From Months to Hours: Droplet Ion Mobility–MS for Biocatalysis Screening</h4>High-throughput screening is central to directed enzyme evolution, but conventional analytical workflows can create a difficult compromise: extremely fast screens often provide limited structural information, while techniques such as LC-MS offer much richer chemical insight at the cost of throughput. In a recent interview, analytical chemist Laura described how her work with droplet-based cyclic ion mobility mass spectrometry is helping bridge that gap—providing rapid analysis while retaining the ability to distinguish structurally similar products.Her research grew from an initially modest proof of concept into a screening platform capable of analyzing a 96-well plate in roughly ten minutes. The resulting workflow was approximately 128 times faster than a conventional three-minute LC-MS analysis, opening new possibilities for directed evolution campaigns in which thousands of enzyme variants need to be evaluated.<h4>Directed evolution needs better analytical screening</h4>Biocatalysis takes advantage of enzymes as highly selective catalysts capable of performing reactions under relatively mild conditions. Directed evolution extends those capabilities by deliberately modifying enzyme sequences, expressing large numbers of variants, screening their activity, and using the best-performing mutants as starting points for subsequent rounds of evolution.The process can be repeated multiple times, progressively steering an enzyme toward improved activity, altered substrate specificity, or even chemistry that does not occur naturally.But the effectiveness of directed evolution depends heavily on the screening step. The more variants that can be analyzed—and the more useful chemical information that can be collected for each one—the more effectively researchers can explore the enormous sequence space available to an enzyme.For Laura, this created a clear analytical challenge: develop a screening platform that was substantially faster than conventional chromatographic analysis without sacrificing the structural discrimination needed for chemically similar products.<h4>From an imperfect first experiment to a working platform</h4>The project did not begin with a polished high-throughput workflow.Laura recalled looking back at her 2023 ASMS poster, where the early system was still working with standards rather than true isomeric samples. Droplet introduction was slow—around six seconds per droplet—and the signals were far from the ideal reproducible, square, flat-topped profiles expected from replicate droplets.Nevertheless, simply producing a droplet signal represented an important first milestone.The decisive change came when the project stopped being treated merely as a demonstration that droplet ion mobility–MS could work and instead became a deliberate effort to build a robust screening platform.Laura approached the problem in modules. First came reliable droplet introduction. Then the ion mobility separation method. Quantification became another independent component. Matrix effects were introduced later, gradually making the system resemble the conditions expected with real screening samples.Each layer was tested before another was added.This stepwise strategy became one of the central principles of the project: rather than attempting to optimize the entire system simultaneously, individual components were developed, challenged, and then assembled into an increasingly realistic workflow.<h4>Finding the middle ground between speed and structural information</h4>One of the biggest analytical problems in high-throughput screening is distinguishing products with the same nominal or exact mass.Constitutional isomers may contain the same atoms and therefore generate the same mass-to-charge ratio, while differing only in how functional groups are arranged within the molecular structure. Very rapid optical or mass-based screens may therefore struggle to distinguish them.Traditional LC-MS can solve many of these problems through chromatographic separation, but a several-minute analysis rapidly becomes impractical when thousands of enzyme variants must be screened.Ion mobility offered Laura’s team another option.Rather than separating compounds on a chromatographic timescale, ion mobility can differentiate ions according to their gas-phase behavior on a much shorter timescale. In the workflow described in the interview, this created a useful compromise: not the kilohertz throughput possible with some simple screening technologies, but dramatically faster structural differentiation than conventional LC-MS.The goal was therefore not simply to achieve the fastest possible screen, but to find a middle-throughput analytical regime with enough resolving power to answer chemically meaningful questions.<h4>A 96-well plate in about ten minutes</h4>That strategy eventually produced one of the most striking results of the project.The droplet cyclic ion mobility–MS platform processed a 96-well plate in roughly ten minutes, while maintaining quantitative results comparable with the conventional LC-MS workflow used for comparison. According to the interview, this represented an approximately 128-fold increase in analysis speed relative to a three-minute LC-MS run.Laura described the successful plate experiment less as a surprise than as confirmation that the modular development strategy had worked.Before reaching that point, the workflow had already been challenged through a sequence of increasingly demanding experiments: droplet formation, ion mobility separation, calibration, matrix-containing calibration, and cross-testing analytes at different concentrations. By the time the complete plate was analyzed, each individual part of the analytical system had already been tested under progressively more realistic conditions.<h4>What does that speed mean for directed evolution?</h4>The impact becomes even clearer when the workflow is considered at the scale of an entire directed-evolution campaign.Laura’s manuscript estimated that a five-round campaign involving 5,000 variants would require approximately 179 days using the conventional LC-MS workflow but only about 14 hours using the new platform.Compressing months of analytical work into less than a day has consequences beyond laboratory productivity.It allows researchers to screen more enzyme variants and therefore sample a larger portion of sequence space. But the resulting datasets may also become increasingly valuable for computational approaches.Rather than retaining information only about the best-performing enzyme variant, researchers can preserve data describing variants that performed poorly as well as those that succeeded. When genotype and phenotype information remain linked through the well-plate workflow, these larger datasets can potentially provide richer input for machine-learning models designed to guide subsequent rounds of enzyme evolution.Faster analysis therefore does more than accelerate an existing experiment—it can change the scale and design of the experiment itself.<h4>Balancing ion mobility resolution and signal</h4>Increasing cyclic ion mobility separation time can improve resolution, but it also introduces an important trade-off: additional passes can reduce signal.Laura optimized this balance experimentally by continuously infusing mixtures containing both isomers and progressively adjusting the ion mobility conditions. After tuning parameters such as wave height and velocity, increasing the separation to three passes provided baseline resolution at the high analyte concentrations used during method development.<blockquote>Concentration, however, also mattered.</blockquote>At higher ion populations, space-charge effects could broaden peaks and reduce the baseline separation. This meant that the optimal number of passes could not be selected independently of the concentration range required by the final assay.Her broader advice for optimization is therefore application-driven: decide first what the analytical method actually needs to accomplish.More speed will almost always require sacrificing something—resolution, signal intensity, quantitative precision, or another performance parameter. The key is to identify which compromise the application can tolerate and then optimize the system around that requirement.<h4>Solving droplet carryover with a practical compromise</h4>Droplet-based workflows present their own engineering challenges, including carryover between neighboring samples.In Laura’s system, analytes showed little tendency to partition into the fluorinated oil separating aqueous droplets within the Teflon tubing. The more troublesome carryover occurred closer to electrospray ionization, where a small amount of sample could remain associated with the interface and appear when the next droplet arrived.Rather than adding excessive engineering complexity to an already elaborate platform, the researchers adopted a pragmatic solution: a sacrificial wash droplet between analytical samples.It is an example of a recurring theme throughout the project. The objective was not to construct the theoretically most sophisticated droplet system, but to create a screening workflow that remained sufficiently robust, reproducible, and practical for large numbers of samples.<h4>High-throughput analysis also requires high-throughput data processing</h4>Accelerating the mass spectrometry experiment created another bottleneck: the data.The instrument produced a continuous intensity-versus-time trace rather than a neatly organized well-plate dataset. With small experiments, Laura could manually identify individual droplets and process the results in spreadsheets. That approach quickly became unrealistic as sample numbers increased.The solution emerged through collaboration with an undergraduate mentee, Aiden, who helped develop a dedicated software tool for processing the continuous traces.Laura defined how the software should behave and how the analytical information should be organized, while Aiden developed the computational implementation. The workflow itself was subsequently adjusted to make automated data processing more reliable—for example, by introducing marker columns that allowed the software to recognize the end of each plate row.The resulting tool can accept the acquired traces together with information about plate dimensions and replicates and automatically return parameters including peak identity, duration, and the corresponding well position. A later version also generated an automatically populated heat map.The experience illustrates how improving analytical throughput often requires simultaneous development of instrumentation, experimental design, and informatics. Making the measurement faster is useful only if the resulting data can be processed at a comparable speed.<h4>Mentoring became part of the scientific process</h4>The software project also reflects another theme Laura emphasized throughout the interview: the value of mentoring.Several younger researchers contributed directly to the development of the final platform. Laura described mentees not simply as additional hands in the laboratory but as scientists capable of proposing their own hypotheses and experimental ideas.Working with undergraduate researchers also influenced the way she organized experiments.Because their available laboratory time was limited, each task needed to have a clear purpose. That encouraged a more disciplined approach to experimental planning: instead of performing experiments simply because they could be done, the team had to ask which experiment would most efficiently answer the next important question.In that sense, mentoring became another mechanism for improving the research itself.<h4>The next step: continuous, automated screening</h4>Despite the dramatic increase in analytical speed, the current workflow still includes manual operations such as loading tubing and connecting the sample stream to the mass spectrometer.The next engineering challenge is therefore automation.Laura described ongoing work using the Venturi effect to pull samples directly from wells into the droplet system. Building on previous work in the laboratory with 96-well plates, she has already tested this approach with as many as 2,000 samples.The long-term direction is clear: continuous and robust droplet generation, automated handling of thousands of samples, rapid ion mobility separation, mass spectrometric detection, and automated reconstruction of the resulting data into plate-based outputs.Combining those elements could move the system closer to the type of large-scale screening required for increasingly ambitious biocatalysis campaigns.<h4>Learning mass spectrometry one problem at a time</h4>Laura also reflected on the broader experience of developing the platform during her PhD.Ion mobility and mass spectrometry initially appeared intimidating, particularly because they combine concepts from analytical chemistry, physical chemistry, separations, instrumentation, and electrical engineering. What eventually changed was not simply learning more facts, but developing the ability to move repeatedly between theory and experiment.An unexpected result sends the researcher back to the underlying theory. A better understanding suggests a modified experiment. That experiment creates another observation, gradually building intuition about how the system behaves.Her advice to early-career scientists is therefore to accept that this process takes time.Advanced analytical techniques may initially appear overwhelming, but understanding develops incrementally through repeated interaction between theory, experimentation, failure, and refinement. Equally important, she emphasized the role of the supportive ion mobility–mass spectrometry community in making a technically demanding field more approachable for young researchers.From the first inconsistent droplets to a platform capable of processing thousands of samples, that iterative mindset ultimately shaped the entire project.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

Determination of nitrosamine content (Bioanalytic)

Our offer includes comprehensive development and validation of methods for determination of nitrosamines in pharmaceutical products. We perform the work according to the criteria and needs of the client based on the EMA note.

Determination of nitrosamines is one of the pharmaceutical industry's top priorities. After the presence of N-nitrosodimethylamine (NDMA) was first reported in an active pharmaceutical ingredient (API), the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) mandated the identification and control of all APIs and finished products in which there is a risk of nitrosamines.The content of nitrosamines in drug products can be controlled primarily by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) analysis. More than that, a reliable analysis result in our offer consists of a well-chosen sample preparation procedure, a selective and sensitive analytical method, and the experience of the analyst, who selects the best method parameters at the optimization stage.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Bioanalytic_Determination_of_nitrosamine_content_Bioanalytic_2_ce4f440837.jpg" alt="Bioanalytic: Determination of nitrosamine content." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Bioanalytic_Determination_of_nitrosamine_content_Bioanalytic_2_ce4f440837.jpg 234w," sizes="100vw" width="1536" height="1024">We have gained experience working with leading pharmaceutical companies. As part of our ongoing work, we have developed analytical methods for small-molecule nitrosamines of 70-150 g/mol. These compounds are mainly formed during manufacturing processes and depend on the presence and type of excipients (e.g. NDBA - N-nitroso-dibutylamine). We have also developed methods for determining molecules with higher nitrosamine drug substance related impurities (NDSRIs). In our work, we focus on achieving the highest possible sensitivity, selectivity and precision. To this end, we individually select the parameters of the methods depending on the composition of the drug and the expected nitrosamines.

Identification of the proteins (Bioanalytic)

We perform proteomic analyses on a state-of-the-art high-resolution ZenoTOF 7600 (SCIEX), in which the Zeno ion trap and EAD (Electron-Activated Dissociation) technology together make a powerful combination.

Protein identification is based on experimental measurement of peptide molecular weights and matching the amino acid sequence of the protein under study with protein sequences deposited in libraries (databases). Two approaches are most commonly used in proteomic studies: top-down and bottom-up. The top-down method involves analyzing full protein sequences. Bottom-up analyses, on the other hand, use digestion of proteins with proteolytic enzymes. The peptides obtained by digestion are analyzed using a mass spectrometer. Each analysis leads to a comparison of experimental data with data obtained by theoretical digestion of proteins described in the database.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Bioanalytic_Identification_of_the_proteins_Bioanalytic_2_6231b73f0d.jpg" alt="Bioanalytic: Identification of the proteins." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Bioanalytic_Identification_of_the_proteins_Bioanalytic_2_6231b73f0d.jpg 245w," sizes="100vw" width="1536" height="766"><h4>LC-MS/MS</h4>Tandem mass spectrometers are commonly used to determine protein sequences. They allow ion selection of pseudomolecular peptides and then fragmentation and measurement of the masses of the resulting fragments. Fragmentation using collision induced dissociation(CID ) is an invaluable tool in targeted and untargeted MS/MS analysis of small molecules. It is important to note that in proteomic analysis, data obtained using the aforementioned fragmentation method may leave gaps. For example, spectra obtained by CID fragmentation do not allow unambiguous differentiation of some amino acids: leucine from isoleucine (identical molar masses and CID fragmentation) and lysine from glutamine (very similar masses). For this reason, we perform proteomic analyses on a state-of-the-art high-resolution <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?manufacturerItems=52&amp;search=+ZenoTOF+7600">ZenoTOF 7600</a> (SCIEX), in which the Zeno ion trap and EAD (Electron-Activated Dissociation) technology together make a powerful combination.

Blind common anabolic steroid and aromatase inhibitors screening – orals (pills, tablets, capsules)

Blind HPLC screening of common anabolic steroids and aromatase inhibitors in pills, tablets, and capsules. The analysis identifies and quantifies all detected target compounds, including mixtures.

The Blind Common Anabolic Steroid and Aromatase Inhibitor Screening is a comprehensive laboratory analysis designed to detect and quantify commonly encountered anabolic-androgenic steroids and aromatase inhibitors in oral products - pills, tablets, and capsules.Because this is a blind analysis, there is no need to specify which substance is expected in the sample before submission. Every target compound included in the screening is assessed, and all detected substances are identified and quantified, including samples containing mixtures of multiple compounds.<h4>About the Target Compounds</h4>Anabolic-androgenic steroids are synthetic derivatives of testosterone or related steroid hormones. They interact with androgen receptors and have both anabolic effects, associated with tissue and muscle growth, and androgenic effects. The screened compounds include substances such as oxandrolone, stanozolol, oxymetholone, methandrostenolone, fluoxymesterone, methasterone, mesterolone, methenolone acetate, and 4-chlorodehydromethyltestosterone. Individual compounds differ considerably in their chemical structure, potency, metabolism, and relative anabolic and androgenic activity.Letrozole, anastrozole, and exemestane are aromatase inhibitors. They inhibit aromatase, the enzyme involved in estrogen biosynthesis, thereby reducing estrogen production. Letrozole and anastrozole are non-steroidal aromatase inhibitors, whereas exemestane is a steroidal aromatase inhibitor.

Blind common anabolic steroid and aromatase inhibitors screening – raws

Blind HPLC screening of common anabolic steroids and aromatase inhibitors in raw API powders. The analysis identifies the target compound and determines its percentage content.

The Blind Common Anabolic Steroid and Aromatase Inhibitor Screening is a comprehensive laboratory analysis designed to identify and quantify commonly encountered anabolic-androgenic steroids and aromatase inhibitors in raw active pharmaceutical ingredient (API) powders.Because this is a blind analysis, there is no need to specify which substance is expected in the sample. The analysis screens for all target compounds listed below and identifies and quantifies any detected substance.<h4>About the Target Compounds</h4>Anabolic-androgenic steroids are synthetic derivatives of testosterone or structurally related steroid hormones. They interact with androgen receptors and produce both anabolic effects, associated with tissue and muscle growth, and androgenic effects. The screening covers testosterone and nandrolone esters, trenbolone derivatives, drostanolone esters, boldenone undecylenate, trestolone acetate, dihydroboldenone cypionate, and several other commonly encountered anabolic steroids.Esterification modifies properties such as solubility and the rate at which a steroid is released after administration. For this reason, the panel includes multiple ester forms of testosterone, trenbolone, nandrolone, drostanolone, methenolone, and other steroid compounds.Letrozole, anastrozole, and exemestane are aromatase inhibitors. They inhibit aromatase, the enzyme involved in estrogen biosynthesis, thereby reducing estrogen production. Letrozole and anastrozole are non-steroidal aromatase inhibitors, whereas exemestane is a steroidal inhibitor.<h4>Key Features</h4><ul><li>Blind screening with no need to declare the expected compound</li><li>Identification of common anabolic steroids and aromatase inhibitors in raw API powders</li><li>Broad panel covering steroid bases, esters, and aromatase inhibitors</li><li>Quantification of the detected target compound</li><li>Analysis by HPLC</li><li>Results reported as percentage content</li><li>Average turnaround time of 7 business days</li><li>Minimum sample amount of 200 mg of raw powder</li></ul><h4>Analysis Parameters</h4><ul><li>Target compounds: testosterone propionate, testosterone phenylpropionate, testosterone isocaproate, testosterone enanthate, testosterone cypionate, testosterone decanoate, trenbolone base, trenbolone acetate, trenbolone enanthate, trenbolone hexahydrobenzylcarbonate, trestolone acetate, nandrolone phenylpropionate, nandrolone decanoate, drostanolone propionate, drostanolone enanthate, dihydroboldenone cypionate, boldenone undecylenate, letrozole, anastrozole, dihydrotestosterone (DHT), exemestane, fluoxymesterone, methandrostenolone, oxandrolone, stanozolol, 4-chlorodehydromethyltestosterone, mesterolone, methasterone, oxymetholone, methenolone acetate, methenolone enanthate, and testosterone base</li><li>Other common names and brand names: Andriolos, Parabolan, MENT, NPP, Deca, BU, Equipoise, EQ, Parenabol, Femara, Arimidex, Aromasin, Halotestin, Halo, Anavar, Var, Winstrol, Turinabol, Proviron, Anadrol, Anapolon, Primobolan, Test E, Test C, Methandienone, Dianabol, and Dbol</li><li>Testing method: HPLC</li><li>Detection limit cutoff: 50%</li><li>Result format: % [98%+, 96%+ or % value such as 94.15%]</li><li>Minimum sample amount: 200 mg of raw powder</li><li>Average turnaround time: 7 business days</li></ul><blockquote>Important Notice: The detection cutoff is 50%.
