Using hydrogen carrier gas to enhance TD–GC–MS methods for semi-volatile organic compounds (SVOCs)
2 Oct 2024Many semi-volatile organic compounds (SVOCs) are considered hazardous to human health. However, traditional reference methods for measuring SVOCs in ambient air are cumbersome and prone to high uncertainty. Markes carried out an investigation to see if there were any benefits or drawbacks of using hydrogen when measuring SVOCs. Explore the results, and find out more about the advantages of using Markes’ Multi-Gas thermal desorption (TD) with gas chromatography–mass spectrometry (GC–MS) and hydrogen carrier gas for the analysis of polycylic aromatic hydrocarbons (PAHs).

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.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.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.Carrier GasEnvironmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and analyze gases or volatile liquids in a sample. It is widely used in environmental testing, food safety, pharmaceuticals, and forensic science. GC is ideal for identifying and quantifying compounds that are gaseous or can be vaporized without decomposition.
