Purge and Trap of Soft Drink - Ethanol Found

contributed by CDS | 05/09/2018

A non-alcoholic beverage is tested by the most sensitive purge and trap method.

It’s no coincidence that the human nose is directly over the mouth, nor that there is an “aromatic” class of organic compounds. While smell is not strictly speaking a component of taste, it certainly can have a significant effect. On the quantitative analytical testing side, the Purge and Trap method can extract and concentrate volatile flavor compounds from a liquid sample for subsequent analysis by GC/MS. In this application, a soft drink was tested with purge and trap-GC/MS on a CDS 7000C purge and trap concentrator coupled to PAL RTC 850 System. The results reveal some interesting findings.
