Körbl用高锰酸银分解产物作催化剂测定有机化合物中碳氢的方法由于填充简单, 燃烧温度低和分析迅速等优点, 近来采用渐广.此法可应用在含卤素、含硫、含磷、合硅以及含氟等有机化合物的分析.在本实验室曾经用这催化燃烧法测定上述数类化合物中的碳和氢, 得到满意结果.Körbl已指出此催化剂能强烈吸收卤素, 因而推想到用此法同时测定碳、氢、卤素三种元素的可能性.

Körbl's catalyst has been used fur the simultaneous determination of carbon, hydrogen and halogens in organic compounds, the catalyst being at the same time the absorbent for the halogens.Presence of nitrogen does not interfere with the determination since the catalyst does not absorb oxides of nitrogen during combustion.The method is simple, rapid and accurate and results obtained on twenty compounds show absolute errors within ±0.3%.
