4 Principles

When a platinum alloy sample with a flat surface is excited by an electric spark discharge, when the atoms or ions of the measured element are excited, the electrons have different energies in the atoms. Level transition, when the transition from high energy state to low energy state produces characteristic spectral lines, by measuring the wavelength and intensity of characteristic spectral lines, according to the The relationship between the intensity of the characteristic spectral line of the measured element and the content was calculated, and the content of the measured element was calculated through the calibration curve. By subtraction, the platinum content. ......
