The main drafters of this standard. Li Jidong, Zhang Ying, Wang Changhua, Sun Zeming, Liu Ying, Chenqiu Lian Feng advanced, Wang Guoliang, Tong Jian, Zang Muwen. High purity ammonium rhenium and rhenium chemical analysis Beryllium, sodium, magnesium, aluminum, potassium, calcium, titanium, Chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium, Determination of indium, tin, antimony, barium, tungsten, platinum, thallium, lead, bismuth content Inductively Coupled Plasma Mass Spectrometry

1 Scope

This standard specifies the high purity ammonium rhenium and rhenium, beryllium, sodium, magnesium, aluminum, potassium, calcium, titanium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium, indium, Tin, antimony, barium, tungsten, platinum, thallium, lead, bismuth content determination. This standard applies to high-purity ammonium rhenium and rhenium, beryllium, sodium, magnesium, aluminum, potassium, calcium, titanium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium, indium, Tin, antimony, barium, tungsten, platinum, thallium, lead, bismuth content was measured. Measurement range. 0.0001% to 0.0050%.

2 Method summary

The sample is dissolved in nitric acid to rhodium internal standard calibration, inductively coupled plasma mass spectrometry directly determined by the working curve method to calculate each Mass concentration of the element, expressed in mass fraction measurement results.
