Laboratory use specifications and test methods GB/T 6682 Analysis
3 PRINCIPLE OF THE METHOD
The samples were microwave digestion, the sample solution introduced into the plasma mass spectrometer. For certain measured ion mass to charge ratio, mass signal in response to the intake
Proportional to the number of ions into the mass spectrometer by measuring the mass of the count signal to determine the concentration of elements in the sample. Using the standard curve method count
Operators element content.
4 Reagents and materials
Unless otherwise indicated, used in the analysis confirmed only for the gifted class pure reagents, laboratory water in line with GB/T 6682 in a water
