Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of experimental detection, in particular to an inductively coupled plasma emission spectrometer. Background Art
[0002] The high-frequency current generated by the high-frequency oscillator in the inductively coupled plasma emission spectrometer is connected to the upper end of the plasma generator tube through the coupling system. When the work starts, the high-voltage discharge device is started to ionize the working gas. When the ionized gas passes through the high-frequency induction coil surrounding the top of the quartz tube, the huge heat energy and alternating magnetic field generated by the coil cause repeated and violent collisions between the electrons, ions and neon atoms in the ground state of the ionized gas. The high-speed movement of various particles causes the gas to be completely ionized to form a coil-like plasma torch area. After the sample is processed into a solution, it is sprayed into the plasma torch from the nozzle through the axial quartz tube. When the sample aerosol enters the plasma flame, most of it immediately decomposes into excited atomic and ionic states. When these excited particles are recovered to a stable ground state, they will release a certain amount of energy. The unique spectral lines and intensities of each element are measured. Compared with the standard solution, the type and content of the elements contained in the sample can be known.
[0003] An exhaust pipe is installed vertically on the top of the plasma emission spectrometer. After the element content is detected, the residual sample will be discharged through the exhaust pipe in the form of aerosol. Usually, an external pipe is used to connect the exhaust pipe to discharge the residual sample out of the room. Generally, a clamp is used for clamping, but this method is not strong enough and is easy to loosen. Utility Model Content
