title: Carbon monoxide analysis: a comparison of two co-oximeters and headspace gas chromatography.
abstract: Three methods (IL-182 Co-Oximeter, IL-282 Co-Oximeter, and headspace gas chromatography) for the analysis of carbon monoxide in postmortem blood were studied and compared using a prepared reference standard, Quantra control materials, and 62 postmortem blood specimens. The methods compared favorably with one another. The linear regression equations for the 62 postmortem blood samples (range = 1.0 to 86% saturation) were: IL-282 vs. IL-182, y = 1.11x - 3.10, r = 0.981; IL-182 vs. GC, y = 0.88x + 2.97, r = 0.973; IL-282 vs. GC, y = 1.00x - 1.24, r = 0.986.
