The Effect of Container Materials on Production of Light Induced Milk – A Study Using SPME-GC-MS

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.

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? 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.
