[The gas chromatographic detection of glycols and their ethers in biological objects during forensic chemical research].
A system consisting of two columns with different separation mechanisms may be used for forensic chemical gas chromatographic analysis of glycols and their ethers: (1) with a polar immobile phase and (2) with a low-polar polymeric sorbent in gas adsorption or gas-liquid adsorption variants. Effects of other volatile solvents associated with glycols and their ethers, of components of technical liquids, blood substituting liquids, decay products on the results of gas chromatographic analysis of the said substances were revealed. The suggested method has been tried in expert studies.
