GC and GCMS webinars - Week 13

This can range from inaccurate results to instruments with significant downtime and high maintenance costs. The guide covers gas analysis from trace level analytes (ppb) that may require preconcentration devices (remote or instrument configured) or specialised detectors all the way up to bulk gas (100%).
<h3>Before Commencement</h3>
<ul>
<li>Ensure you understand the requirements of the analysis and sampling</li>
<li>If the instrument is not configured or cannot conform to your analysis requirements it may require modification or renewal (please refer to <a href="https://gcms.labrulez.com/library?search=%20Analytical%20Instrument%20Purchasing%20Quick%20Reference%20Guide">Analytical Instrument Purchasing Quick Reference Guide</a>)</li>
<li>The instrument has been installed to manufactures specification and all maintenance logs/service history are current and up to date.</li>
</ul>
<h3>Sample State</h3>
The sample state is the next item to consider. How can you introduce this into the gas chromatographic process in a safe and representative way to produce accurate and reliable results? 
The sample maybe from a reaction process and may not be at ambient temperature and pressure. 
There also maybe other compounds or the matrix that will interfere and either at best compromise results or actually react with the materials in the sample path. These are additional questions you should ask.
<ul>
<li>Vessel (Type, size, material, connections, seals/caps) </li>
<li>Sample pressure &amp; temperature (range)</li>
<li>Sample stability &amp; storage</li>
</ul>
<h3>Instrument Configuration</h3>
The configuration of a gas analysis GC could be simple a one injector , one column and one detector, however most tend to be a little more complex that are provided with plumbing diagram in order to understand what is happening and also to troubleshoot any problems that may occur. 
<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Schema_zapojeni_a_ventilovy_diagram_plynoveho_chromatografu_pro_analyzu_plynu_26f8b32b4a/Schema-zapojeni-a-ventilovy-diagram-plynoveho-chromatografu-pro-analyzu-plynu.png" alt="ChromSolutions: Plumbing diagram of the valve GC system for Gas Analysis"/>
There maybe additional hardware such as methanizers/Jetanizer which can convert an inert gas to methane for a greater response on an FID. 
Valves maybe plumbed upstream of a injector to enabled variations in sample loading. 
Flows also maybe changed/diverted, analytes trapped and this may involve multi port valves and/or pressure switching.
<h3>Gas Sample Path/Introduction</h3>
Firstly if your sample is from an above temperature and pressure (e.g. reactor) you want this to be introduced directly and should use a valve. In this case you may have to consider the use of trace heating lines to the instrument and temperature/pressure ratings of the valves. 
<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Ventil_pro_plynovy_chromatograf_pro_analyzu_plynu_e9d6d0e232/Ventil-pro-plynovy-chromatograf-pro-analyzu-plynu.png" alt="ChromSolutions: A Valve for Gas Analysis"/>
The other ways to introduce your sample is by a syringe. 
Both can be manual or automated. Automated is always a better option with regard to repeatability and valves are a preferred choice as the ingress of air can be minimised, through purging the loop and if necessary purging the valve housing. Rotary and diaphragm are the choices.
Typical sample volumes are between 0.25 - 1.0ml.
When sampling several different sample points a stream selection valve maybe incorporated into the GC configuration. 
Manual sampling/injection using a syringe (gas tight or glass to glass seal) can have safety and analysis implications from pressurised vessels and directly introduced into GC injection ports.
The compatibility of material that comes in contact with the sample always needs to be considered particularly on analytes and matrices that absorb or react on these surfaces.
<h3>Columns</h3>
Pick column dimensions and material, and phase which depends on the application.
<ul>
<li><a href="https://gcms.labrulez.com/library?search=Packed">Packed</a> (1/4”, 1/8”, 1/16”) or capillary (0.25mm - 0.53mm)</li>
<li><a href="https://gcms.labrulez.com/library?search=porous">Porous polymers</a>, <a href="https://gcms.labrulez.com/library?search=molecular%20sieve">molecular sieves</a>, thick film liquid phase columns</li>
</ul>
Porous polymers come in a range of polarities and molecular sieve columns are specifically to separate O₂ and N₂ and can separate H₂/He, CO &amp; CH₄. CO₂ and &gt;C₂ will not elute from molecular sieve columns. 
Conditioning and upper temperature limits may vary dramatically so care maybe needed when they are located in the same oven.
<h3>Detectors</h3>
There are some specifically used for gas analysis such as TCD, PDHID, IMS and PED, however PFD/PFPD/SCD, FID and MS are used in certain applications.
<h3>Conclusion</h3>
If these guidelines are considered you will encounter fewer issues with your gas chromatograph and gas analysis results.

<h3>Before Commencement</h3>
<ul>
<li>Ensure the new or existing instrument is configured and installed with the correct supplies, gases, column(s) and injector(s), valve(s), liner(s), detector, interfaces and software options for detection of the target analytes.
</li>
<li>The instrument has been installed to manufactures specification and all maintenance logs/service history are current up to date.
</li>
</ul>
<h3>Initial Testing</h3>
<ul>
<li>Ensure data capture method has sufficient speed to comply with accuracy requirement (8 points min across a peak for 5-10% repeatability).
</li>
<li>Adjust column flows and oven temperature profile to achieve the required sample throughput and separation for a mid range standard.
</li>
<li>Optimise detector conditions for best response and minimal interference.
</li>
<li>Optimise injector parameters for best response, chromatographic resolution and minimal peak distortion.
</li>
<li>Apply data processing method to obtain the correct integration parameters and identification windows for the chromatography.
</li>
<li>Adjust auto sampler settings and to obtain optimal repeatability (min 6 injections) on a mid range standard.
</li>
<li>If the method criteria cannot be reached for the mid range standard consider increasing data capture speed and/or the addition of internal standard(s).
</li>
</ul>
<h3>SQC &amp; Sample Testing</h3>
<ul>
<li>Inject a matrix matched standard or a sample (min 6 injections) to check identification, integration and repeatability.
</li>
<li>If the chromatograms/results differ significantly from the initial testing or than expected/acceptable, consider a more appropriate matrix elimination strategy.
</li>
</ul>
<h3>Carry Over Testing</h3>
<ul>
<li>Inject high std +20% followed by a blank and measure carry over and carry over re-peatability. Also ensuring overloaded peak shapes is kept to a minimum.
</li>
<li>Modify autosampler parameters and wash solvents/purge gas to minimise carry over.
</li>
<li>Modify data processing method to ensure correct integration of high level standard and blanks.
</li>
<li>Run a sample or independent QC standard six times with new auto sampler conditions to compare chromatography and repeatability data to the initial SQC and sample testing. If not comparable re-adjust modifications made in carry over tests.
</li>
</ul>
<h3>Calibration/QC/Validation Considerations</h3>
<ul>
<li>Initial Calibration for external/internal standard and mole %/normalised %.
</li>
<li>Run calibration range from low std 3*limit of detection and top std max level +20% (ideally 7 point). Run 3 points at each level, 6 points at LOQ, 6 points at mid point and 6 points at highest level. Plot calibration curve and assess linearity criteria and calculate % rsd at levels containing 6 points.
</li>
<li>If any adjustments are made to the method the sample or independent QC/sample spikes need to be recalculated or re-injected.
</li>
<li>Devise a QC/validation protocol with independent QC and calibrations to ensure method robustness and the control of the frequency of the maintenance procedures. Typical protocols include injection of low and high level standards/SQC’s/sample spikes measuring peak areas, retention times and peak shapes. In addition baseline noise and offsets from chromatogram start and end are typically measured.
</li>
</ul>

GC and GCMS webinars - Week 17

Pesticides are chemicals that are very closely monitored and may not always be easy for an analytical chemist to monitor and detect.
Thanks to their use in agriculture and subsequently also their cycle in environment we can find them almost everywhere. The variety of analyzed matrices is so wide, ** detection limits ** are pushing down and the field of analytical chemistry is also under pressure on sample throughput, and thus also the efficiency and economy of methods.
Instrumental techniques are also being developed hand in hand with these requirements, and we will look at the latest possibilities of gas chromatographs (GC) in connection with triple quadrupole mass spectrometers (GC/QQQ) in this overview.
We will focus on 2 main areas of these analyzes, namely food and the environment, in which you can then filter in more detail in the library, eg by combination with other techniques or take a closer look at <a href="https://gcms.labrulez.com/library?search=pesticides&amp;date=2019-2021&amp;instrumentationItems=3-4-15-10">sample preparation</a> and suitable <a href="https://gcms.labrulez.com/library?search=pesticides&amp;date=2019-2021&amp;instrumentationItems=3-4-15-19">GC columns</a>. 
All documents can be found <a href="https://gcms.labrulez.com/library?search=pesticides&amp;date=2019-2021&amp;instrumentationItems=3-4-15&amp;publicationTypeItems=1-2-7-5-4">directly for download in our LabRulezGCMS library</a> and to complement possible analytical techniques you can also explore similar applications using liquid chromatographs (LC) in connection with triple quadrupole mass spectrometers (LC/QQQ) in an article on the <a href="https://lcms.labrulez.com/article/1276">LabRulezGCMS portal </a>. 
Today, you will find almost 13,000 documents in the field of analytical chemistry and separation techniques in libraries, and their number is growing every day.

GC and GCMS webinars - Week 18

Liquid chromatography and gas chromatography coupled with mass spectrometry (LC/MS, GC/MS) are two major analytical techniques for identifying compounds in complex mixtures. This symposium provides a forum for experts from industry, academia and government agencies to share their novel experimental methods, creative data analysis techniques including mass spectral library searching and software development, and the applications of these techniques, with special emphasis on the use of LC/MS/MS in metabolomics, proteomics, lipidomics, forensics, pharmaceutical and environmental studies.
<h3>Abstract</h3>
For the last 20 years, Eastman has routinely employed the NIST search for the identification of unknowns. Initially, we primarily utilized EI searches, but in recent years, the increase in the availability and quality of tandem libraries plus associated software has greatly enhanced LC-MS library search results. More than 50 instruments and associated users are networked at Eastman world-wide. Our corporate library of &gt;55K entries in NIST format is automatically updated and distributed nightly.
The 2020 edition of the NIST library utilized with the NIST MS 2.4 search software offers many major enhancements. NIST for the last six years has had an ambitious program to acquire and analyze targeted chemicals (&gt;50,000). In addition, the novel <a href="https://gcms.labrulez.com/article/1128">hybrid GCMS EI and MSMS search</a> and <a href="https://lcms.labrulez.com/article/1110">LC/MS/MS Hybrid Search</a> expands the scope of all EI and tandem libraries.
