The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.

1 Scope

This section YS/T 276 provides for arsenic, aluminum, copper, cadmium, iron, lead, thallium, tin, zinc, bismuth determination of indium.

This section applies to the determination of indium arsenic, aluminum, copper, cadmium, iron, lead, thallium, tin, zinc, bismuth content was measured in the range of 0.00010% ~ 0.0050%.

2 Principle of the method

The sample is dissolved in nitric acid in acid medium, using ICP-MS- standard addition calibration and the use of added scandium, rhodium, rhenium mixed internal standard method of measurement Given indium arsenic, aluminum, copper, cadmium, iron, lead, thallium, tin, zinc, bismuth content.

3 Reagents

Unless otherwise indicated in the analysis using recognized as excellent pure reagents and distilled or deionized water or equivalent purity. Laboratory are fully cleaned thoroughly soaked with water containers with a solution of nitric acid (119).

3.1 nitric acid (rho = 1.42g/mL), MOS level.

3.2 nitric acid solution (11).

3.3 nitric acid solution (19).
