The working process of atomic emission spectroscopy

Atomic emission spectroscopy includes three main processes:
     The light source provides energy to evaporate the sample, form gaseous atoms, and further excite the gaseous atoms to generate light radiation;
     The composite light emitted by the light source is decomposed into spectral lines arranged in order of wavelength by the spectroscopic system to form a spectrum;
     A detector is used to detect the wavelength and intensity of the spectral lines in the spectrum.
     Its working principle is that the sample solution atomizes the liquid sample through the atomizer of the sampling device, enters the ICP, and is excited by the ICP torch to generate composite light. The spectroscopic system decomposes it into a spectrum arranged by wavelength. The spectral intensity at the position is converted into an electrical signal, and then the data is collected and processed by the computer, and finally the analysis result is displayed on the screen or printed out.
