Comprehensive screening of volatile emissions from plastics

This study demonstrates the use of a discovery platform combining thermal desorption with GCxGC–TOF MS for comprehensive screening of emissions from plastics. The platform was used to uncover ‘hidden’ compounds that would have been overlooked using conventional GC–MS techniques.

The enhanced separation of GCxGC provides cleaner spectra for confident identification of key analytes. For example, the four compounds highlighted in the figure would have co-eluted with the high-loading aliphatics in a 1D separation.
