Haloacetic acids (HAAs) are disinfection byproducts (DBPs) formed when drinking water is chlorinated to remove microbial contents. Chlorine reacts with naturally occurring organic and inorganic matters (decaying vegetation) in water leading to formation of DBPs that include HAAs. There are nine different HAAs anticipated, of which five HAAs are currently regulated: monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), trichloroacetic acid (TCA), monobromoacetic acid (MBA), and dibromoacetic acid (DBA). The remaining four HAAs, which are not regulated, include bromochloroacetic acid (BCAA), bromodichloroacetic acid (BDCAA), dibromochloroacetic acid (DBCAA) and tribromoacitic acid (TBAA). However, they are also of health concern and are often analyzed along with five regulated HAAs.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_New_Column_for_Fast_Analysis_of_Haloacetic_Acids_Bromate_and_Dalapon_Using_Ion_Chromatography_Coupled_with_Mass_Spectrometry_c99b1d5940.jpg" alt="Thermo Fisher Scientific: New Column for Fast Analysis of Haloacetic Acids, Bromate and Dalapon Using Ion Chromatography Coupled with Mass Spectrometry" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_New_Column_for_Fast_Analysis_of_Haloacetic_Acids_Bromate_and_Dalapon_Using_Ion_Chromatography_Coupled_with_Mass_Spectrometry_c99b1d5940.jpg 245w," sizes="100vw" width="1200" height="600">According to the U.S. Environmental Protection Agency (EPA), there is increased risk of cancer associated with long-term consumption of water containing a level of HAAs that exceeds 0.06 mg/L. EPA methods 552.1, 552.2, and 552.3 are used to determine all 9 HAAs in drinking water and require derivatization and multiple extraction steps followed by gas chromatography (GC) with electron capture detection (ECD). In comparison to the GC method, the combination of ion chromatography and mass spectrometry (IC-MS) provides sensitive and rapid analysis without the need for sample pre-treatment. To facilitate a simple and easy-to-use direct injection method, the U.S. EPA published EPA Method 557 for the analysis of haloacetic acids, bromate, and dalapon in drinking water by IC-MS/MS.<h4>Column selection for HAAs analysis</h4>The <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/order/catalog/product/064153">Thermo Scientific Dionex IonPac AS24 column</a> was specifically designed to separate HAAs from the matrix components (chloride, nitrate, carbonate, and sulfate) in drinking water samples. The Dionex IonPac AS24 column provides high capacity, allowing large loop injection of complex samples without overloading the column, while maintaining excellent peak shapes for lower concentration analytes, which eliminates the need for sample pretreatment when analyzing HAAs in high-ionic strength matrices. The Dionex IonPac AS24 column (in 250 mm × 2 mm i.d. format) was the first column written into EPA Method 557. While the Dionex IonPac AS24 column meets all the requirements for EPA Method 557, the analysis time for this column is close to 1 hour. For increasing the sample throughput, it was advantageous to design a new column for the HAAs analysis to reduce overall run time, therefore, research and development efforts were focused on designing a new high-capacity column with optimized selectivity to allow direct injection of high ionic strength samples and reduced analysis time closer to 30 minutes.That new column, launched under the name of Thermo Scientific Dionex IonPac AS31 column, was designed to provide optimum selectivity for 9 HAAs relative to matrix ions at 15°C for reproducible recoveries of HAAs and to allow chloride, carbonate, and sulfate to elute as a single peak (Figure 1) with an optimum hydroxide eluent gradient profile. Advanced stationary phase chemistry resulting in unique selectivity helped to reduce the analysis time without compromising column capacity and provided the opportunity to divert high concentration matrix anions from the MS source, thus avoiding signal suppression in mass spectrometry detection. The column capacity of the Dionex IonPac AS31 column is comparable to that of the Dionex IonPac AS24 column, thus also enabling large loop injection of high concentration samples without straining the column while preserving superb peak shapes and resolution for all 9 HAAs.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Figure_1_Comparison_of_Dionex_Ion_Pac_AS_31_and_Dionex_Ion_Pac_AS_24_column_sets_5176eee9c3.jpg" alt="Thermo Fisher Scientific: Figure 1 - Comparison of Dionex IonPac AS31 and Dionex IonPac AS24 column sets" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Figure_1_Comparison_of_Dionex_Ion_Pac_AS_31_and_Dionex_Ion_Pac_AS_24_column_sets_5176eee9c3.jpg 245w," sizes="100vw" width="1200" height="600">One of the key advantages is that Dionex IonPac AS31 column provides approximately 39% shorter run times relative to the Dionex IonPac AS24 column, reducing U.S. EPA Method 557 run time from 57 minutes to approximately 35 minutes.Since the release of Dionex IonPac AS31 column, several application notes have been published to take advantage of this column for the analysis of HAAs, bromate and dalapon (Table 1). As demonstrated in AN73343, the Dionex IonPac AS31 column meets or exceeds the EPA Method 557 requirements using the Thermo Scientific TSQ Fortis MS.<ul><li>AN 73342: <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_73342_ic_ms_haloacetic_acids_bromate_dalapon_water_an73342_en_4d427888a7.pdf">Determination of low-level haloacetic acids, bromate, and dalapon in drinking water using IC-MS</a></li><li>AN 73343: <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_73343_ic_ms_haloacetic_acids_bromate_dalapon_water_an73343_en_cda05a3077/an-73343-ic-ms-haloacetic-acids-bromate-dalapon-water-an73343-en.pdf">Fast determination of nine haloacetic acids, bromate, and dalapon at trace levels in drinking water samples by tandem IC-MS/MS</a></li><li>AN 73390: <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_73390_ic_hram_haloacetic_acids_bromate_dalapon_drinking_water_an73390_en_a8ad5bfa8b/an-73390-ic-hram-haloacetic-acids-bromate-dalapon-drinking-water-an73390-en.pdf">Determination of haloacetic acids, bromate, and dalapon in drinking water using ion chromatography coupled to high-resolution accurate-mass (IC-HRAM) mass spectrometry</a></li></ul>The unique selectivity and high capacity of the Dionex IonPac AS31 column makes it an ideal column for the development of specialized applications. Using gradient elution with KOH eluent, this column provides excellent separation of environmental anions including inorganic anions, oxyhalides, oxyanions, and organic acids (Figure 2).<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Figure_2_Capabilities_of_the_Dionex_Ion_Pac_AS_31_column_Ion_Chromatography_and_Mass_Spectrometry_for_HA_As_analysis_fee630bf87.jpg" alt="Thermo Fisher Scientific: Figure 2 - Capabilities of the Dionex IonPac AS31 column Ion Chromatography &amp; Mass Spectrometry for HAAs analysis" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Figure_2_Capabilities_of_the_Dionex_Ion_Pac_AS_31_column_Ion_Chromatography_and_Mass_Spectrometry_for_HA_As_analysis_fee630bf87.jpg 245w," sizes="100vw" width="1024" height="512">To fully utilize the advantages of Dionex IonPac AS31 column and support its backpressure under the standard operating conditions, it is recommended to use <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/410">Thermo Scientific Dionex ICS-6000 HPIC system</a> equipped with an electrolytic eluent generator and Low Temperature DC Detector/Chromatography Compartment capable of maintaining a column temperature of 15 °C.

New Column for Fast Analysis of Haloacetic Acids, Bromate and Dalapon Using Ion Chromatography Coupled with Mass Spectrometry

The year 2025 marks the golden jubilee of ion chromatography (IC), a technique that has revolutionized analytical chemistry and impacted numerous fields globally. As we celebrate 50 years of IC, it’s worth reflecting on its origins, advancements, and significant contributions to science and industry.<h3>Celebrating anniversaries with ion chromatography</h3>What is the traditional first-anniversary gift? It’s paper, which signifies a new beginning, a blank page for a new start. We see paper used everywhere, every day, but not often do we think about how it is made. Paper is made through a process of making pulp from cellulose fiber, such as wood. Chemicals are used in this process to bleach and color the paper according to demand. Ion chromatography plays an important role in analyzing inorganic anions, organic acids from the pulping process, and carbohydrates from the wood.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://ippta.co/wp-content/uploads/2021/01/IPPTA-172-49-54-Ion-Chromatography.pdf">IPPTA Jouma12005; (No.2): Ion Chromatography – The Technique and its Applications in Pulp and Paper Industry</a></li></ul>Cotton, the gift for the second anniversary, signifies growth, as the threads intertwine to make it stronger. Cotton production relies on ion chromatography to ensure smooth processing. For example, IC is used to measure carbohydrate limits for melezitose and trehalulose deposits on cotton from insects.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://www.researchgate.net/publication/305718393_Separation_and_Quantitation_of_Plant_and_Insect_Carbohydrate_Isomers_Found_on_the_Surface_of_Cotton">AATCC Journal of Research 3(4):13-23: Separation and Quantitation of Plant and Insect Carbohydrate Isomers Found on the Surface of Cotton</a></li></ul>For the third anniversary, the traditional gift is leather for durability. For centuries, we have had leather shoes and clothing in their natural color.&nbsp; Nowadays, leather is often treated with chromium to create vibrantly-colored goods, like blue leather shoes! With the limits of hexavalent chromium getting lower for drinking water, it is also important to limit hexavalent chromium in leather, as it can affect us from direct skin contact. IC is essential for this analysis.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/AB_107_Determination_Hexavalent_Chromium_Dyes_AN_70393_E_9417787acf/AB-107-Determination-Hexavalent-Chromium-Dyes-AN70393-E.pdf">Determination of Hexavalent Chromium in Dyes</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/AB_202_IC_Hexavalent_Chromium_Drinking_Water_AB_71978_EN_9f428dce11.pdf">Sensitive Determination of Hexavalent Chromium in Drinking Water Using a Compact Ion Chromatography System</a></li></ul>In the fourth year, the traditional gift can be flowers or fruits, suggesting a blossoming relationship or a fruitful journey. When we give a gift of agricultural produce, we need to think about the possible contamination of pesticides. Ionic polar pesticides are known for being challenging to analyze, often involving long and tedious sample preparation and derivatization. However, we now can simplify this analysis by using ion chromatography and mass spectrometry (IC-MS).<ul><li><a target="_blank" rel="noopener noreferrer" href="https://assets.thermofisher.com/TFS-Assets/CMD/brochures/br-002387-ic-icms-anionic-cationic-polar-pesticides-br002387-na-en.pdf">Accurate, Reproducible Anionic and Cationic Polar Pesticide Quantitation</a></li></ul>At 5 years, the gift is wood, representing solid longevity and wisdom. This ties back to year one with the paper. By year five, the knowledge that is written on the paper will grow into a book.Jumping to year 10, we have tin or aluminum, which symbolizes strength, durability, and perseverance. In many metal analyses, ion chromatography is not the first choice of technique until speciation is required. Post-column chemistry is often used to speciate metals while IC is chosen for its inert flow path to handle the aggressive chemicals that are used. Sometimes, it is coupled to an inductively coupled plasma mass spectrometer for speed and simplicity.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/AN_69_b79a88fca9/AN69.pdf">Determination of Aluminum in Complex Matrices Using Chelation Ion Chromatography</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/AN_1142_IC_AN_71750_EN_86cac4b223/AN1142-IC-AN71750-EN.pdf">Determination of Aluminum in OTC Pharmaceutical Products</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://www.sciencedirect.com/science/article/abs/pii/S0021967314015568">Journal of Chromatography A: Speciation analysis of inorganic tin by on-column complexation ion chromatography with inductively coupled plasma mass spectrometry and electrospray mass spectrometry</a></li></ul>To step up to the next big anniversary milestone, the 25th is where we go into the precious metals, silver! It symbolizes brilliance, purity, strength, and beauty. How do I associate silver with ion chromatography? Silver reference electrodes are used for cyanide analysis. This is an important test given the toxicity of inorganic cyanides.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_000779_ic_cyanide_by_ic_ed_an000779_na_en_e0b7f9e114/an-000779-ic-cyanide-by-ic-ed-an000779-na-en.pdf">Determination of Cyanide in Alkaline Solutions Using Ion Chromatography</a></li></ul>Finally, we arrive at the golden jubilee, celebrating 50 years. Gold represents wisdom, prosperity, and strength. My understanding is half a century of learning and growth. But how does gold fit into ion chromatography?

What is the Ion Chromatography Golden Jubilee? Celebrating 50 Years of IC Innovation

This year marks a special milestone: the <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/article/5341">50th anniversary of ion chromatography (IC)</a>, a technique that has transformed how we separate and analyse ions, driving innovation across environmental, food, and pharmaceutical applications.Over the decades, IC has continually evolved with smarter, more powerful hardware—but its impact grew even stronger when paired with <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/76">Chromeleon software</a>. This combination didn’t just streamline workflows; it elevated IC into a more intuitive, connected, and reliable solution for laboratories worldwide.On a personal note, my connection with IC and Chromeleon software goes back 20 years. In my first lab job when I was still at university, I often performed bench test analyzes to determine sulphate – a process that could take several hours. When the laboratory decided to invest in its first IC system, it was a game changer! It was clear from the start that the combination of IC and Chromeleon software is not only logical — it’s historical – they complemented each other so well that they reshaped the way I understood data, automation, and efficiency in the lab.As both have evolved throughout the years, so has my appreciation for what they can do together. In fact, some of my favorite features in Chromeleon software were directly inspired by working with IC—functionalities that I’ll share in this blog, showing why, even after so many years, IC and Chromeleon software remain an unbeatable team. Let’s go:<h3>1. One report for all your data</h3>In modern analytical labs, data volume is not the challenge — data clarity is. Scientists don’t just need results; they need results that can be compiled, compared, and validated across multiple runs, detectors, and even instruments.This is where Chromeleon software’s reporting capabilities shine. With dual sequence processing capabilities, enabling merging of data to provide more comprehensive results, Chromeleon software condenses complexity into a single report. The ability to compare multiple sequences in one window transforms how scientists interpret data: instead of managing multiple files or juggling disconnected reports, they see the complete analytical story at once.For example, scientists can directly compare cation and anion analyses performed with conductivity detectors in a single report, or merge results from different detectors—such as conductivity and mass spectrometry (MS)—to view all findings in one cohesive output. These practical applications highlight how Chromeleon software simplifies workflows while delivering deeper scientific insight.In regulated industries, this clarity is not just convenient — it’s critical. Chromeleon software ensures that reporting adheres to compliance requirements, producing audit-ready documentation while still being practical for everyday use.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Ion_Chromatography_Turns_50_Chromeleon_Software_s_Tribute_to_a_Lifelong_Partner_ec4aeb624d.jpg" alt="Thermo Fisher Scientific: Ion Chromatography Turns 50: Chromeleon Software’s Tribute to a Lifelong Partner" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Ion_Chromatography_Turns_50_Chromeleon_Software_s_Tribute_to_a_Lifelong_Partner_ec4aeb624d.jpg 234w," sizes="100vw" width="1024" height="683"><h3>2. Beyond conductivity detection</h3>One of the defining strengths of ion chromatography has always been its versatility. But when coupled with MS, it steps into an entirely new dimension. IC–MS allows scientists to go beyond the classic seven anions detectable by conductivity, enabling the identification of additional species such as bromate and chlorate with high selectivity and sensitivity.For many laboratories, dual detection is no longer a luxury — it’s a necessity. Regulatory environments demand precision, trace-level sensitivity, and the ability to differentiate analytes in complex matrices. Chromeleon software makes this practical by seamlessly integrating multiple detectors—including conductivity, UV, amperometry, and MS.This flexibility enables advanced applications such as <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/AN_491_63068_Glycophosphate_in_water_0e9c57b8d8/AN491_63068_Glycophosphate-in-water.pdf">pesticide residue analysis using ion chromatography coupled with tandem mass spectrometry (IC–MS/MS)</a>. By unifying all data into one platform, Chromeleon software streamlines complex workflows and turns them into clear, actionable results. Instead of facing a fragmented dataset, users get a unified, intuitive view. The software ensures that IC–MS doesn’t just produce powerful results — it produces results that are accessible, reviewable, and ready for decision-making. For readers seeking to dive deeper into this capability, Thermo Fisher Scientific has published a detailed white paper on <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/wp_73175_ic_ms_wp73175_en_d5fcfb30b4.pdf">IC–MS workflows</a>.<h3>3. Ensuring instrument health and longevity</h3>Behind every robust analytical result is an instrument that’s running smoothly. In chromatography, hardware issues can easily compromise data quality — or worse, disrupt entire workflows with unexpected downtime.Chromeleon software acts as a proactive safeguard by monitoring system health in real time. Parameters like pump pressure oscillations can be continuously tracked, visualized in intuitive charts that reveal subtle shifts before they escalate into problems. For example, a gradual rise in pump pressure may signal a blockage or worn consumable — insights that allow labs to intervene early, extend the life of their equipment, and minimize costly downtime.This functionality transforms Chromeleon software from being “just” a data system into an instrument health partner. Much like a fitness tracker helps athletes stay in peak condition, Chromeleon helps IC systems operate at their best, ensuring continuity, reliability, and efficiency.<h3>Conclusion: For many more years to come!</h3>Ion chromatography and Chromeleon software share more than just history. Together, they form a partnership that amplifies the strengths of each: IC delivers separation power and analytical depth, while Chromeleon software provides the intelligence to manage, interpret, and safeguard results. The outcome is not just better data — it’s better science, delivered with confidence.In an era where laboratories face growing complexity, tighter regulations, and higher expectations for efficiency, the synergy between IC and Chromeleon software is more relevant than ever. It’s not just a story of two technologies — it’s a blueprint for how innovation and integration can shape the future of analytical science. Happy Golden Jubilee, my friend 😊<h5>Learn more:</h5><ul><li><a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/products-and-services/promotions/industrial/chromatography-evolution/ic-evolution.html">IC Evolution</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/webinar/5386">Webinar: Reduce manual integrations: Optimize data processing with detection parameters and algorithms</a></li><li>Visit us on&nbsp;<a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/showcase/72003132/admin/dashboard/">LinkedIn:</a>&nbsp;#IonChromatography #ChromeleonCds #compliance #MassSpectrometry</li></ul><section><blockquote><h5>Laercio Fernandes</h5>Laércio Fernandes is a Product Marketing Manager for software at Thermo Fisher Scientific.
