Application Note: enhancing the performance of SPME and sorptive extraction for GC–MS using trap-based preconcentration

This study shows how GC–MS performance for the sampling of aroma compounds and off-odours in beverages can be enhanced by using techniques incorporating trap-based preconcentration.

As a readily-automated, fast, solvent-free technique, solid-phase microextraction (SPME) has become widely adopted for a broad range of samples and applications, including analysis of foods and beverages, profiling of aromas and off-odours, as well as environmental, clinical and industrial investigations.
