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
5.1 Ultra-pure water. meet the GB/T 6682 in the laboratory water level specifications, while the resistivity is greater than 18MΩ · cm.
5.2 hydrofluoric acid. mass fraction of 40%, MOS grade high purity reagent.
5.3 nitric acid. mass fraction of 65%, MOS grade high purity reagent.
5.4 nitric acid solution (2 98). take 20mL nitric acid, slowly add 980mL of ultra-pure water.
5.5 Standard Storage Solution for Aluminum, Calcium, Iron, Sodium, Potassium, Titanium, Magnesium, Chromium, Nickel, Boron, Manganese, Copper, Scandium Element. 1000 μg/mL, respectively.
