用ITHAC-2002仪器测定金属铬中的氢
DETERMINATION OF H2IN METAL CHROME BY ITHAC─2002
-
摘要: 通过试验,实现了ITHAC-2002仪对金属铬中氢的测定。对分析电流,分析时间,脱气电流,脱气时间,梯度时间等进行了逐一选择。方法标准偏差为0.46%,变异系数为3.36%。Abstract: In the experiment,the ITHAC-2002 was used to determine H2 in metal chrome,Options of analysis current,analysis time,degassing current,degassing time and gradient time were made one by one. The standard deviation was 0.46% and variation factor 3.36%.
