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 6682 Analytical laboratory water specifications and test methods Clean rooms and associated controlled environments - Part 1. Air cleanliness class

3 Principle of the method

The samples were digested with hydrofluoric acid and analyzed by inductively coupled plasma mass spectrometry in nitric acid medium. Inductively coupled plasma mass spectrometer from Sub-source and mass spectrometer two parts. The sample solution is atomized by the carrier gas into the ion source torch flame, after evaporation, dissociation, atomization, electricity From the process, into a positively charged ions, through the acquisition system into the mass spectrometer, mass spectrometer according to the mass to charge ratio separation. For certain The mass-to-mass ratio is proportional to the number of ions entering the mass spectrometer. The concentration of the sample is proportional to the area of the mass spectrum Standard series is more quantitative.

4 interference factors

4.1 In the course of the test there are usually two-atom ions, multiple ions, matrix effect, background noise, interference between elements, cross-contamination and instrumentation Drift and other factors. 4.2 Sampling, sample preparation and analysis of the purity of the reagent, the cleanliness of the equipment and the introduction of pollution during the operation will also affect the test results.

5 reagents and materials
