The differences between DIMS and GC approaches are presented.

Ensuring that volatile leachable impurities are at low levels in polymeric materials is very important for minimizing migration to food and pharmaceutical products.

For the BTEX compounds, detection limits in the single-digit parts-per-billion concentration range (by volume) are readily achievable within seconds using selected ion flow tube mass spectrometry (SIFT-MS), because sample analysis is achieved without chromatography, preconcentration, or drying.
