在高纯铼制品上取样,样品经过清洗和干燥后,使用辉光放电质谱法检测元素含量,辉光放电质谱法为半定量分析,纯度单位为ppm。
Samples are taken from high-purity rhenium products. After the samples are cleaned and dried, the element content is detected by glow discharge mass spectrometry. Glow discharge mass spectrometry is a semi-quantitative analysis, and the purity unit is ppm.
