Characterisation of paint samples by direct desorption TD–GC–MS

In accordance with indoor air quality guidelines, paint manufacturers test VOCs emitted from their products once applied to a surface and cured. Some manufacturers also determine the VOC and SVOC content of the raw materials or final product, as this complements emissions testing in terms of assessing the potential for toxic or harmful compounds to be released over time.

Direct thermal desorption of materials is ideally suited to this type of sample introduction, and it allows selective preconcentration of the compounds of interest prior to analysis by GC(MS).

This application note describes the application of direct thermal desorption for the analysis and quantitation of volatile organic chemicals and semi-volatile organic chemicals in dried and ‘wet’ paint samples.
