[The development of the conditions for the direct gas chromatographic determination of ethyl alcohol in cadaveric material].
Conditions for direct gas chromatographic analysis of ethyl alcohol using a device with flame ionization detector have been developed. The presence of other C1-C5 alcohols or alcohol surrogates (acetone, aromatic carbohydrates, organochlorine compounds) did not impede ethanol measurement. Comparison of the accuracy and reproducibility of the routine ethylnitrite and the new direct gas chromatographic analyses showed that the two methods are similar by their metrological parameters and time needed for the measurement. At the same time, use of direct (without ethanol derivation) analysis helps eliminate the contamination of the working area with harmful gases, including nitrogen oxide and alkylnitrites. The above methods of analysis were used with various objects of expert evaluation, including putrescent organs and tissues. Putrefaction products did not influence the accuracy and reproducibility of ethanol measurement.
