This is a microchromatographic method for simultaneous determinations of O2, N2, CO2 and N2O in gas samples of 40-100 microliters. A Packard 836 U gas chromatograph with a thermal conductivity detector and helium gas as carrier was used. The combination of Porapak and 5A molecular sieve column system was found adequate and is described in detail. The fidelity of this method was proved by a high constancy of the retention time, the linearity of the response and the reproducibility of results. The present method proved to be reliable for determination of all middle ear gases in man and experimental animals during general anesthesia with N2O.
这是一种用于同时测定40 - 100微升气体样品中O2、N2、CO2和N2O的微型色谱法。使用了配备热导检测器且以氦气作为载气的帕卡德836 U气相色谱仪。发现Porapak和5A分子筛柱系统的组合是合适的，并对其进行了详细描述。该方法的准确性通过保留时间的高度稳定性、响应的线性以及结果的可重复性得到了证明。本方法被证明对于在使用N2O进行全身麻醉期间测定人和实验动物的所有中耳气体是可靠的。
