Determination of carbon monoxide , carbon dioxide and hydrocarbon in the gases - part 3 : determination of total hydrocarbon in gases - flame ionization method 气体中一氧化碳二氧化碳和碳氢化合物的测定第3部分:气体中总烃的测定火焰离子化法
This method can only be applied to roughly test impurity content of test samples due to relatively big deviation produced by peak area normalization method 由于峰面积归一化法测定误差大,因此,本法通常只能用于粗略考察供试品中的杂质含量。
In this paper , a varieties of purification processes are carefully discussed according to three methods of synthesis of diphenyl carbonate 摘要本文按合成碳酸二苯酯的三种方法光气法、酯交换法和氧化羰化法,详细介绍了碳酸二苯酯的提纯工艺。
