Various plastics used as barriers to the production of off-flavors in light exposed milk were examined using HS-SPME with a new Carboxen®/PDMS coated Nitinol fiber followed by GC-MS analysis allowing detection of low MW analytes at levels <1 ng/mL.

实验方案

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

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。

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.
