Analysis of ethylene glycol (eg), propylene glycol (pg), and diethylene glycol (deg) using gas chromatography and the luma™ multi-channel vacuum ultraviolet (vuv) detector

The presence and quantification of Ethylene Glycol (EG), Propylene Glycol (PG), and Diethylene Glycol (DEG) in consumer products are a crucial concern due to their potential toxicity to humans. While these compounds are commonly used in a variety of applications, from antifreeze to cosmetics, their ingestion or absorption can have harmful health impacts, with DEG being especially harmful.

This technical brief introduces a streamlined approach to this analysis using LUMA, an advanced gas chromatography detector that leverages vacuum ultraviolet (VUV) spectroscopy. The method uses 1,3- Propanediol as an internal standard, providing accurate and reliable quantification. This approach aligns with the FDA’s method but employs LUMA’s unique capabilities to simplify the process and increase the robustness of the analysis.
