4.How it works
Inductively Coupled Plasma emission spectrometer, also known as ICP spectrometer (Inductive Coupled Plasma), takes inductively coupled high-frequency plasma as the excitation light source, uses the atomic or ion emission characteristic spectrum of each element to determine the composition of the substance, and carries out qualitative and quantitative analysis of the element. Also known as ICP atomic Emission spectrometer. The atomic emission spectroscopy analysis process is mainly divided into three steps, namely excitation, spectroscopy and detection.
The first step: The excitation light source vaporizes the sample, dissociates or decomposes into an atomic state, and the atoms may also be further ionized into an ionic state. Atoms and ions in the light source excited light;
The second step: use the splitter to disperse the light emitted by the light source into a spectrum arranged by wavelength;
The third step: The use of photoelectric devices to detect the spectrum, according to the measured spectral wavelength of the sample for qualitative analysis, or according to the intensity of the emitted light for quantitative analysis.
