DETERMINATION OF CARBON MONOXIDE IN BLOOD BY HEAD SPACE ANALYSIS

Determination of carbon monoxide in blood by head space analysis.

A method for the determining the amount of carbon monoxide (CO) in blood is described. CO bound to hemoglobin is released with potassium ferricyanide into a known volume of head space of a disposable syringe. Vapor in the head space is withdrawn with a gastight microcyringe and injected into the gas chromatograph. CO dissolved in saturated blood is also measured by head space analysis to ascert...

The Determination of Carbon Monoxide in Blood

Determination of carbon monoxide in blood.

Methods suggested for the determination of carbon monoxide in blood may be considered as belonging to either of these two classes: first, those in which the relative content of carbon monoxide in blood is measured; second, those in which the absolute quantity of carbon monoxide per given quantity of blood is determined. In the first class, the result is expressed as the percentage saturation of...

Quantitative determination of carbon monoxide in blood by gaschromatography.

The gaschromatographic determination of CO in blood has been simplified by using carbon molecular sieve columns for separation of gases. Regeneration of the columns is necessary only after 1000 and more analyses. Moreover, a more simple procedure for evaluating the CO concentration was developed. This procedure is suitable for routine determination in the sensitivity range of 0.2—100 % COHb in ...
