What does inductively coupled plasma atomic emission spectrometer mean?
The high frequency current generated by the high frequency oscillator is connected to the tubular coil with water cooling in the copper at the upper end of the plasma generating tube via the coupling system. Three coaxial argon flows through the channel in the plasma generating tube made of quartz. The cooling gas (Ar) stabilizes the plasma torch and the cooling quartz tube wall through the external and intermediate channels surrounding the plasma, preventing the tube wall from melting and heating.
After the sample is processed into a solution, the atomizer is changed into a full sol from the bottom into the tube, and the quartz tube is injected into the plasma torch from the nozzle through the center shaft. When the sample aerosol enters the plasma flame, most of the sample breaks down into the atomic and ionic states of the excited state. When these excited particles recovered to a stable ground state to release some energy (performance spectra for a certain wavelength), determination of spectral line specific to each element and strength, compared with the standard solution, you can know the types and contents of elements contained in the sample.
The working gas (Ar) is composed of quartz pipe into the middle, started work at a high pressure discharge device to start gas ionized and ionized gas through the high-frequency induction coil around the quartz tube at the top of the coil, the enormous heat and the alternating magnetic field, electrons, ions and ionized gas in the ground state of the Ne atom repeated violent collisions, high-speed movement of all kinds of particles, resulting in gas ionization completely to form a similar coil shaped plasma torch area, where the temperature is as high as 6000 to 10000 degrees celsius.
