摘要
本文采用脉冲色谱法测定金属铬中的氢含量,用正交试验法选择了最佳分析条件(含加热时间、加热初级电流、试样重量、浴料及浴比),建立了锡浴法测定铬中氢的方法。方法精度为5.5%。
The present article illustrates themetbod for determining the hydrogen con-tent in metallic chromium by impulse heat-ing-gas chromatography.It established theoptimum conditions for analysis by orthogo-nal design including heating current,heatingduration,sample weight,bathing materialand bath ratio. Tin bath is used for the de-termination of hydrogen in chromium with aprecision of 5.5%。
