[Evaluation of a reference chromatographic method for the determination of blood levels of carboxyhemoglobin].

The FID chromatographic analysis of methane obtained by the catalytic reduction of CO on nickel is a valuable method for the quantity control of the HbCO analyzer in clinical routine. For Hb levels between 9 and 18 g%, the coefficient of variation for the chromatographic method is to 2% for HbCO ranging from 100 to 2%, and 2 to 6% for HbCO ranging from 2 to 0.2%. A simple method for the extraction of blood CO is evaluated.
