Table 1 Element and measurement range Analysis element Determination range (mass fraction) /% Pb Sn Bi Sb As 0.00010 to 0.0050 0.00010 to 0.0050 0.00010 to 0.0050 0.00010 to 0.0050 0.00010 to 0.0050

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. GB/T 4010 Ferroalloy chemical analysis of the sample to take and preparation GB/T 12806 laboratory glass instrument single standard line capacity bottle GB/T 12807 Laboratory glass instruments - Index pipettes GB/T 12808 Laboratory glass instruments Single line suction pipette

3 principle

The samples were decomposed with dilute sulfuric acid, and the solution was atomized and introduced into an inductively coupled plasma mass spectrometer. The mass spectra of the analytical elements in the solution were measured The mass fraction of the analytical element is calculated from the calibration curve made with the standard solution. Calibrate the blank and calibrate the solution to the subject of the sample to be tested Element and sample decomposition with the acid matrix matching, indium as the internal standard calibration instrument sensitivity drift and matrix effect.

4 reagent

Unless otherwise stated, only high purity reagents or equivalent purity of less than 0.00005% of each of the elements to be measured are used in the analysis Reagents. ......
