The Performance of Thermal Desorption for the Quantitative Analysis of Long-chain Hydrocarbons

This study investigates the ability of Markes’ thermal desorption (TD) systems to monitor semi-volatile organic compounds (SVOCs), using a wide range of
n-alkanes (n-C₁₆ to n-C₄₄) as a model. The application note explains how modern TD technology delivers robust and repeatable results for compounds across this wide boiling range and can, therefore, be used to enhance GC–MS analysis of trace SVOCs in air and other matrices. It is also shown how highly repeatable
re‑collection of TD samples is a convenient approach to validating analyte recovery in accordance with standard methods.
