Performance of Thermal Desorption for Quantitative Analysis of Long-Chain Hydrocarbons
4 Dec 2018This 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. Markes demonstrate 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's also shown how highly repeatable re-collection of TD samples is a convenient approach to validating analyte recovery in accordance with standard methods.

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.
