Detailed instrument composition and working principle
The ICP plasma reflection spectrometer consists of a monochromator, radio frequency generator, sample introduction system, photoelectric conversion, control system, data processing system, and analysis and operation software. The plasma is generated in a triple concentric quartz torch. Argon gas is introduced into the torch in a tangential direction. The upper part of the torch is wound with a copper load coil (with cooling water inside). When the high-frequency current generated by the high-frequency generator (operating frequency 40MHz, power is about 1KW) passes through the coil, it generates The alternating magnetic field ionizes a small amount of argon gas to generate electrons and ions. Under the action of the magnetic field, it accelerates and collides with other neutral atoms, generating more electrons and ions, forming eddy currents in the torch, and forming a plasma torch under the action of electric sparks ( That is plasma), the temperature of this plasma can reach more than 10000K. The aqueous solution to be tested enters the central channel of the quartz torch through a sprayer to form an aerosol. Atoms are ionized under the action of external energy, but the atoms in the excited state are very unstable. When they transition from a higher energy level to the ground state, they will release huge energy, which is radiated in the form of electromagnetic waves of a certain wavelength. Different elements produce different characteristic spectra. These characteristic spectra are projected onto the grating in the spectrometer through the lens. The calculation is performed by controlling the stepping motor to rotate the grating, and the transmission mechanism accurately locates the light intensity of the characteristic spectral line of the element to be measured after the spectroscopy at the exit slit. The spectral line light intensity is converted into electric current, and then after circuit processing and V/F conversion, the data is processed by the computer, and finally the analysis result is printed out by the printer.
