Plasma is a very common concept in modern physics. It is a gas that is ionized to some extent (with a degree of ionization greater than 0.1%). The concentration of electrons and cations is in equilibrium and is macroscopically charged. Neutral substance.
Inductively coupled plasma (ICP) is a high-frequency electric current generated by a high-frequency current through an induction coil, which makes the working gas form a plasma, and presents a flaming discharge (plasma torch), reaching a high temperature of 10000K, which is a good evaporation. - A spectral source of atomization-excitation-ionization properties. Moreover, since the plasma torch has a ring structure, it is advantageous to inject from the plasma center channel and maintain the stability of the flame; a lower carrier gas flow rate (less than 1 L/min) can penetrate the ICP, so that the sample is The central channel has a residence time of 2 to 3 ms, which can be completely evaporated and atomized. The high temperature of the central channel of the ICP ring structure is higher than the temperature of any flame or arc spark. It is the optimal excitation temperature of atoms and ions, and the analyte is at the center. The channel is indirectly heated, which has little effect on the ICP discharge property; the ICP source is a light source with a small self-priming phenomenon and no electrode discharge, no electrode contamination. These features make the ICP source an excellent analytical performance that meets the requirements of an ideal analytical method.
