3 Method summary
The sample was processed as an electrode, the sample with the excitation system and the counter electrode excitation light, and the beam splitting system is introduced,
Through the dispersion element is decomposed into a linear spectrum. The intensity of the internal standard line and a selected line of analysis photoelectrically converted and measured according to the standard sample
Standard curve, the computer automatically collect excitation strength values and calculate the amount of analyte in the sample analysis.
