How does etg testing work?
Ethyl glucuronide (EtG) is a direct metabolite of ethanol alcohol. The presence of EtG in the urine can be used to detect recent alcohol consumption, even after the ethanol alcohol is no longer measurable. The presence of EtG in the urine demonstrates that ethanol alcohol was ingested within the past three or four days, or roughly 80 hours after the ethanol alcohol has been metabolized by the body. As a result, it can be determined that a urine alcohol test employing EtG is a more accurate indicator of the recent consumption of alcohol as opposed to simply measuring for the existence of ethanol alcohol.

How do people use chromatography in food testing?
There are many applications - from the characterisation of oils and fats (cis-trans and saturated/unsaturated etc..) to the analysis of traces of pesticides and herbicides in fruit and vegetables. Nowadays the connection of a GC to a mass spectrometer is relatively inexpensive and gives more specificity. Liquid chromatography extends the range of analytes such as many toxins (aflatoxins etc) which are unsuitable for GC and for example flavanoids in foods
