Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
Plasma is generated from the triple concentric quartz tube in a torch. Argon is put into Torch pipe in tangent direction, the upper part of torch is coiled with copper loop <intercom cooling water>. High-frequency generator generates the high frequency current (40 MHz frequency around 1 KW power) through the coil, producing around Alternating magnetic field, ionizeing to produce a small amount of argon ion and electron, in the magnetic field under the accelerated collisions with other neutral atoms, producing more electronic and ions, in the form of eddy current, EDM reacts in the plasma formed under the plasma torch( That is, plasma). The plasma temperature could be up to 10000 K or higher. Aqueous solution measured by the formation of aerosol spray into the center of the quartz torch channel. Atomic is ionized by energy of outsiders, but the atoms are in unstable state, and from the high-level transition to the ground state, atoms will release tremendous energy, this energy is a certain wavelength of electromagnetic radiation and is sent out. Different elements have different spectral characteristics. These feature spectrum shoots grating of spectrometer through the lens, computer rotates grating by controlling the stepper motor, transmission mechanism posit elements characteristic spectra accurately to the slit, and photomultiplier change the spectrum of light intensity to the current, then deal with the circuit and V / F conversion by computer data processing, the final analysis is made by the printer.
ICP inductively coupled plasma single-channel scanning spectrometer, is a multi-element analysis of the sequence test measuring equipment. The instrument consists of scanning spectrometer, radio frequency generator, the sample introduction system, photoelectric conversion, control systems, data processing systems, and analysis software.
