A sensitive and reproducible gas chromatographic method for ethanol and other volatile organic compounds in serum or plasma was developed using the polar CP- Wax 52 CB column, creating good peak shapes; this can also be seen for ethylene glycol.
This document presents a sensitive and reproducible gas chromatographic method for analyzing alcohols, acetaldehyde, and acetone in serum and plasma. The method is particularly useful for forensic and toxicology laboratories and involves the direct injection of biological specimens with minimal pre-treatment. It specifically addresses the analysis of ethylene glycol, which can cause toxic effects such as renal dysfunction.

The ethanol concentration of plasma is 1.17 times the concentration in whole blood.
It should typically be cleaned or changed after about 50 injections to prevent performance decrease.
