Gas chromatographic method of quantitative determination of carbon monoxide in cadaver blood

A gas chromatographic method has been developed for measurement of carbon monoxide in cadaveric blood on a chromatographer with thermal conductivity detector and air oxygen as the internal standard. The error of the method is no more than 4% with the mean quadratic deviation +/- 0.18-0.33 min. The method was studied on 10 model and 30 expert blood samples. Putrefactive products did not influence the accuracy of analysis.
