Using thermal desorption for industrial (stack) emissions testing
Application Note 077
Stack gases are often aggressive matrices comprising both high- and low-concentration organic vapours with acid gases, high levels of particulates, high humidity and a wide range of inorganic gases. Another challenge is that no two stack samples are alike.
This application note covers selection of the appropriate organic vapour sampler for the analytes of interest in stack gas sampling, and optimisation of the subsequent sampling and thermal desorption (TD)–GC analytical process.
Also discussed are the benefits of thermal desorption against solvent extraction.
