有机碳氢微量分析法虽已有很多改进,但似尚缺一种既能用以测定挥发性又能测定非挥发性有机化合物中碳氢含量的装置.最近已有改进的测定固体及挥发性物质中碳氢的方法[1,2],但该装置专为测定含氟化合物中的碳氢含量而设计.本文应用如图1的根据经验及综合前人方法制定的装置,分析若干挥发性及非挥发性液体与固体有机化合物以及元素有机化合物中碳氢含量,结果都令人满意(见表1).

A modified apparatus for the quantitative determination of carbon and hydrogen contents of either volatile or non-volatile substances is introduced.The part of the modified apparatus for the entrance of the sample (Fig.1) is lengthened in such a way that the strongly volatile sample can be cooled before analysis without any loss and that the non-volatile liquid or solid sample can be heated electrically to render complete volatilization.Furthermore,the modified apparatus can also be used for the analysis of substances containing tin,arsenic,sulfur,fluorine and other halogens.
