3 Principle
The sample and the mixed flux are mixed in proportion, and melted at a high temperature to obtain a precious metal granule, which is sequentially dissolved by dissolving precious metal with nitric acid and aqua regia.
A solution of gold, platinum, or palladium. Determination of the signal value of an element in the above solution by inductively coupled plasma mass spectrometry (ICP-MS) using an internal standard
Method of quantification. The concentration of the element in the solution is proportional to the signal value of the instrument within the measurement range of the element.
