An on-line analytical method of gas chromatography for determination of total carbon in pure hydrogen produced by PSA was studied.

利用带镍加氢转化炉的气相色谱仪 ,在线分析变压吸附法制纯氢中的总碳。

In order to determine the total carbon in ultrafine silicon carbide powder, the national standardis the burning -weight method.

测定碳化硅中的总碳量，国标法踝用燃烧—重量法，即用四氧化三铅作助熔剂，此创熔剂在加热过程中易溢出使结果受影响，并且与磁燃烧管熔在一起使燃烧管破损量增加，不能连续测定，本文采用钨锡合金作助熔剂，分析结果表明这种助熔剂是可行的。
