用高錳酸銀热分解产物复盖在試样上进行灼烧和用同一試剂作固定填充剂并采用較高的氧气流速能使有机物在三分钟內氧化完全.为闡明燃烧过程, 故比較本法、Körbl法和套管热分解法所产生的二氧化碳热导曲线.此外, 尚討論燃烧温度、氧气流速和复盖的氧化剂所起的作用.

In the present communication, a modification of the combustion method for the microdetermination of carbon and hydrogen was described, in which the sample was covered with the thermal decomposition product of AgMnO47 and the combustion tube was filled with the same reagent.By using this method, most of the organic compounds can be decomposed approximately in three minutes.
