[A simple extraction chamber for the analysis of gases by gas chromatography in small blood samples (50 microliters) (author's transl)].
A sample extraction chamber for the determination of O2- CO2- and N2O-concentrations in 50 microliters blood samples by gas chromatography is described. These blood samples can be transferred anaerobically from the ear lobe of a patient or other donor by a doctor or medical auxillary. It is shown that N2O, O2 and CO2 are completely extracted from blood, red cell suspension and HCO3-solutions respectively. When the concentrations of the same sample was repeatedly measured the coefficient of variation was 1.3% for O2 and N2O and 1.2% for CO2.
