适用性

application for SPME

应用

food and beverages

分析说明

Beverages are liquid, so sample preparation is often simple, and can be accomplished with direct injection, headspace, solid phase microextraction (SPME), solid phase extraction (SPE), or liquid-liquid extraction (LLE). SPME coupled with GC is an effective technique for monitoiring the volatiles present in the headspace over spirits.
