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. The first part of the study focuses on SPME, and how trapping and enrichment can improve peak symmetry, qualitative analysis and sensitivity. The second part of the study compares these methods against automated robe-based high-capacity sorptive extraction, which as well as being operationally robust, ffers improved recovery for higher-boiling compounds and an extended analyte range.
