摘要
RO-416型氧测定仪用氧化锌基准试剂校正后,用于测定钨合金中的氧。利用RO-416型氧测定仪在输入1.000 g质量时测量范围是0.0％～4.5％的特点,分析质量为0.003～0.006g的氧化锌基准试剂,手动输入1.000g质量,测得氧含量为0.06％～0.12％,与钨合金粉末中的氧含量接近。用氧化锌基准试剂校正仪器是可行的。
Zinc oxide primary reference material ( PRM ) of 0. 003-0. 006 g was analyzed to use the scope of RO -416 oxygen determinalor being 0. 0%-4.5% when inputting 1.000 g PRM as the mass value. The oxygen determined in zinc oxide PRM was 0.06%-0. 12% when inputting 1.000 g PRM manually as the mass value, approaching the oxygen in the tungsten alloy powder. The test result proved that the method is feasible by using zinc oxide PRM to calibrate the instrument.
