A modified method for the analysis of carbon monoxide in postmortem blood.

A simple spectrophotometric method is given for the determination of carbon monoxide in postmortem bloods. Duplicate determinations take about 15 minutes and are shown to be unaffected by the presence of methemoglobin. The method is therefore particularly suitable for use in a forensic laboratory. The results obtained are compared to those from the method of Commins and Lawther.
