2 principle of the method
After the sample excitation light source, the radiation characteristics of the light through the entrance slit to the dispersion into a spectrum splitting system, the spectral intensity and element content was
A certain function. Selected on the strength of internal standard line and the analytical line to photoelectric measurements, prototyping work according to the standard curve, can be obtained
Measuring the content of the element.
