The SelectScience Editors are pleased to announce a complimentary, live educational webinar entitled “From Helium to Hydrogen: GC-MS Case Study on SVOCs in Water,” featuring guest speakers Alexander Semyonov and Jessie Butler from Thermo Fisher Scientific.

The analysis of semi-volatile organic compounds (SVOCs) in water, specifically U.S. EPA Method 8270, involves identification and quantitation of more than 120 analytes of varying chemical structure, polarity and volatility. The diversity of the analytes in this method presents particular challenges when migrating from helium to hydrogen carrier gas.

This presentation will discuss the key modifications to both GC and MS set up necessary for the successful migration to hydrogen carrier gas and will examine the effect of each parameter on data quality. A case study for the fast GC-MS analysis of SVOCs will be presented, as well as the final optimized method fully migrated to hydrogen carrier gas.

In this webinar you will learn the key differences in the physical properties of helium and hydrogen as they apply to GC-MS and acquire troubleshooting skills and knowledge about using hydrogen as carrier gas in GC-MS. In addition you will learn the best practice of analyzing SVOCs in water, including fully developed, tested, and validated U.S. EPA Method 8270.

Ami Miller, Associate Editor at SelectScience, will be leading a live Q&A session following the webinar.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. EPA MethodsEPA methods are procedures approved by the U.S. Environmental Protection Agency for monitoring and analyzing environmental pollutants, including air, water, and soil samples. These methods are critical in ensuring public health and environmental safety.
