Beware of GC Column Bleed: Tips and Tricks for Troubleshooting Bleed Problems

Join us as we distinguish between abnormal and normal GC column bleed as well share some tips and tricks to control your GC column bleed.

GC Column Bleed: Tips & Tricks & Troubleshooting

Separation Science, in collaboration with Thermo Fisher Scientific, offers the third instalment of its &#39;Instrument Selection Discussion Series&#39; where Laboratory Professionals gain knowledge on the choices of instrument available and which is most recommended for specific applications. In the final edition, we look at considerations around the choice of carrier gas in gas chromatography.
The helium supply chain crisis has negative implications on research and laboratory operations worldwide. Helium rationing, delayed deliveries and price increases still cause difficulty in production planning and uncertainty in instrument productive uptime. This affects laboratory productivity and this expert discussion shares insights on optimum use and the selection of carrier gas.
<h3>By watching this expert discussion you will learn about:</h3>
<ul>
<li>carrier gas choices for GC
</li>
<li>benefits and limitations of using hydrogen versus helium
</li>
<li>benefits of gas generators versus other gas sources
</li>
<li>what is involved in converting from helium to hydrogen in the laboratory
</li>
<li>user benefits that can be realized, particularly with respect to cost savings, using new GC instruments
</li>
<li>innovative solutions that can be expected in GC in the future
</li>

Carrier Gas Selection in Gas Chromatography

In the Thermo Scientific 'Instrument Selection Discussion Series', we look at considerations around the choice of carrier gas in gas chromatography.

1,4-Dioxane is an industrial chemical contaminant that is of concern even at trace levels in consumer products. Government jurisdictions are beginning to regulate the amount of 1,4-dioxane allowed in consumer products globally. It has already been banned and deemed unsafe in cosmetics in Canada, and it is a regulated substance in Europe. The allowable concentrations in the United States are expected to vary from state to state, typically at part per billion to low part per million levels.
There have been several methods developed to test for 1,4-dioxane, but none of these methods are adequate to detect 1,4-dioxane in consumer products with complex mixtures and solutions. A method for the high-sensitivity detection of 1-4-Dioxane was developed on the Agilent 8890B/7000 GC/QQQ triple quadrupole in Electron Ionization (EI) mode. The extraction was performed using an Agilent PAL3 autosampler with solid phase microextraction (SPME) tool. The GC was configured with a 30 m DB-8270D column and a 1 m deactivated fused silica column using a purged ultimate union. The advantage of using a tandem quadrupole mass spectrometer is that a selective precursor to product ion transition is generated, minimizing interferences. Analysis time was less than 15 minutes. Calibration curves using 9 levels from 0.1 ng/g (ppb) to 400.0 ng/g (ppb) in multiple reaction monitoring (MRM) Electron Ionization with an R2 value of 0.999. Low detection limits, necessary for these pernicious compounds, were also achieved.

This webinar will overview a sensitive method used to analyze semivolatile organic compounds (SVOCs) on an Agilent 7000E Gas Chromatograph/Triple Quadrupole (GC/TQ) Mass Spectrometer. The utilization of GC/TQ instrumentation for analysis of SVOCs offers significant advantages:
<ul>
<li>Excellent selectivity afforded by Multiple Reaction Monitoring (MRM) mode results in faster batch review and increased confidence due to the elimination of matrix interferences often present when using GC/MS acquisition modes; and 
</li>
<li>Better sensitivity enables smaller extraction volumes which improves sustainability, reduces waste, and decreases costs associated with sample preparation, solvent usage, and waste disposal.
</li>
<li>Key analytical techniques which facilitated this work will be discussed.
</li>
<li>Manufacturer’s recommended tune protocol for mass accuracy and resolution checks in accordance with US EPA Method 8270E will also be discussed.

A calibration curve or regression is always plotted with the instrument responses on the dependent vertical (y -) axis and the standard concentrations on the horizontal (x -) axis. As a linearity of calibration regression minimizes random errors of the instrument, we aim to find the best straight line to pass through these calibration points.
<ul>
<li>What are the estimated errors and confidence limits we can estimate for the slope (or gradient) and the y-intercept of the line?
</li>
<li>What is the uncertainty of the analyte concentration found on the calibration curve?
</li>
<li>What are the least concentration of the measurand can be detected with, say 95% confidence?
</li>
<li>In other words, what is the limit of detection (LOD) of this method?
</li>

Uncertainty of Linear Calibration Curve & Detection Limit

Oral fluid has emerged as a popular biological matrix for analysis due to its non-invasive nature and ease of sample collection. However, the analysis of oral fluid samples becomes challenging due to the presence of the excipients, surfactants, and preservatives in the collection buffer. These additives are necessary to ensure the stability and authenticity of the sample during collection and transport. However, the presence of these additives can foul the optics of the mass spectrometer and diminish the signal response of the analyte panel if the samples are not cleaned up adequately before injection.
In this webinar, Shahana Wahab Huq, senior application scientist at Phenomenex, will present an effective sample cleanup method for oral fluid analysis that targets 32 pain panel analytes and results in good precision, accuracy, and linearity over 300 fold dynamic concentration range.
<h5>Key learning objectives</h5>

Driven by the urgency of climate change, hydrogen is perceived as a critical solution to pave the way for a low-carbon future. Ideally, green hydrogen produced entirely from renewable energy will serve as a clean and sustainable fuel but other colours of hydrogen, such as blue hydrogen, will also play a key role by facilitating the energy transition toward the Hydrogen Economy.
Shimadzu provides practical solutions for building a feasible hydrogen supply chain, from hydrogen production to transportation and storage.
In this webinar, learn about the different colours of hydrogen, the end-to-end process of a hydrogen supply chain, and how Shimadzu&#39;s instruments can help harness the potential of hydrogen as the fuel of the future.
<h5>Learning Objectives:</h5>
<ul>
<li>Understand how Hydrogen Economy plays a critical role toward a low-carbon future</li>
<li>Shimadzu&#39;s solutions in constructing a feasible hydrogen supply chain</li>
