实验方案

DRO, EPH, ETPH, GRO, PRO, PVOC, STARS, TPH, VPH? Help, I’m Trapped in Alphabet Soup!

There are three types of analyses: GRO, DRO, and TPH. The published methods are simply variations of these to meet the different analytical needs of the individual agencies.

Determination of Headspace Volatiles in Distilled Spirits Using SPME Coupled to GC

In this article, SPME-GC was successfully used to identify many volatile compounds present in the headspace over several spirits.

DRO、EPH、ETPH、GRO、PRO、PVOC、STARS、TPH、VPH？救命啊！我被困在字母汤里啦！

分析方法主要分为三种：GRO，DRO和TPH。上述发表的方法只是这些方法的变种来满足各个机构的不同分析需求。
