[Quantitative determination of ethylene glycol using head-space chromatography]

A simple, easy to do, and precise method in the determination of ethylene glycol in biological material is presented. After oxidation of ethylene glycol with sodiummetaperjodate is the resulting formaldehyde with sodium-borhydride to methanol reduced. The stoechiometric amount of resulting methanol is determined by Head-Space-Gaschromatography. The determination is made with peakheight method.
