提出了一种分离和测定羰基化合物2,4-二硝基苯腙的气相色谱方法。该方法代表了现有技术的修改版本，现有技术容易热分解，因此不适合精确的定量工作。所提出的方法提高了检测器响应的精度和线性度，表明样品的热分解减少了。简述了该方法测定汽车尾气中羰基化合物的应用。
A gas chromatographic method for the separation and determination of carbonyl compounds as their 2,4-dinitrophenylhydrazones is presented. The method represents a modified version of existing techniques which are prone to thermal decomposition and hence are not amenable to accurate quantitative work. The precision and linearity of detector response has been improved in the method presented indicating that thermal decomposition of the samples was decreased. Application of the method for the determination of carbonyl compounds in auto exhaust is described briefly.
