A gas chromatographic determination of benzene and toluene in blood with a small amount of blood sample, 0.02 or 0.1 ml, is described. In the method an aliquot of the blood sample in a sealed hypodermic syringe of 2 ml capacity is equilibrated at 37 degrees C in a thermo-regulated water-bath. After establishing equilibrium 1 ml of overlying air is submitted to gas chromatographic analysis. The value of this method was verified by experiments in which men, rabbits, and rats were exposed to benzene and toluene mixtures of various concentrations.
本文描述了一种气相色谱法，用于测定少量血液样本（0.02或0.1毫升）中的苯和甲苯。该方法是将2毫升容量的密封皮下注射器中的一份血液样本在37摄氏度的恒温水浴中平衡。达到平衡后，取1毫升上层空气进行气相色谱分析。通过对人、兔和大鼠暴露于不同浓度苯和甲苯混合物的实验验证了该方法的有效性。
