Foreword

This standard is in accordance with GB/T 1.1-2009 given rules drafted. Instead of the standard YS/T 35.1 ~ 35.4-1992 "high purity chemical analysis of antimony." The Standard 35.4-1992, compared with 35.1 ~ major changes YS/T as follows. --- The original standard was amended to integrate, four combined into one, with high-quality resolution glow discharge mass spectrometer of high purity chemical antimony ingredient. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is mainly drafted by. Emei Semiconductor Material Factory. Involved in the drafting of this standard. Beijing Nonferrous Metal Research Institute, Lanzhou Jinchuan New Material Technology Co., Ltd. The main drafters of this standard. Chenggao Ming, Li Jidong, Sun Ping, Qinfang Lin, Yang Weidong, Dingguo Jiang, Liao Min, Ding Cui, Qiu Ping. This standard replaces the standards previously issued as follows. --- YS/T 35.1 ~ 35.4-1992. High-purity chemical analysis of antimony Magnesium, zinc, nickel, copper, silver, cadmium, iron, sulfur, arsenic, gold, Determination of manganese, lead, bismuth, silicon, selenium content High resolution glow discharge mass spectrometry

1 Scope

This method specifies the purity w (Sb) ≥99.999% antimony in high purity magnesium, zinc, nickel, copper, silver, cadmium, iron, sulfur, arsenic, gold, manganese, lead, bismuth, silicon, Determination of Selenium Content. This method is applicable purity w (Sb) ≥99.999% antimony in high purity magnesium, zinc, nickel, copper, silver, cadmium, iron, sulfur, arsenic, gold, manganese, lead, bismuth, silicon, Determination of selenium content. Determination of the elements in the range of 1.0 × 10-7% ~ 1.5 × 10-4% (w%).

ASTME135 define the following terms apply to this document. 3.1 High-resolution high-massresolution Mass resolution greater than 3500.

4 Method summary

4.1 Principle of the method The sample is mounted to a plasma discharge chamber, and samples were sputter. Splash out from the surface of the sample atoms are ionized, poly Coke ion beam by double-focusing magnetic sector mass analyzer. At this point, mass spectrometry (ion flux) or by magnetic acceleration voltage (or both) of sweep He described the collection. 4.2 Analysis 4.2.1 Quality Mi isotope ion current is measured by subtracting the total ion current contribution portion from all other sources of interference. Portion The measured ion flow may only be derived from the ion detector (detector noise). Another part may be derived from the measured impurity element endless mass resolution And the whole mass close to, but not equal to Mi ion signal interference element or molecule. In all these cases, the interference must contribute part Evaluation, and should be deducted from the measured signal. 4.2.2 If you can not clear interference in the measurement of ion flow Mi part of the premises, the measured ion flow minus identify the source of interference Section, obtained as a result of the detection limit for this impurity elements.
