Using hydrogen carrier gas to enhance TD–GC–MS methods for semi-volatile organic compounds (SVOCs)

Many 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).
