![]() ![]() In the induction zone it can even reach 10000 K. The plasma is extremely hot, 6000-7000 K. Due to collision between the argon atom and the electrons ionization occurs, giving rise to a stable plasma. As a consequence, an alternate magnetic field is induced which accelerated electrons into a circular trajectory. In the ICP-OES the plasma is generated at the end of a quarts torch by a cooled induction coil through which a high frequency alternate current flows. Plasma is the forth state of matter, next to the solid, liquid and gaseous state. ![]() The produced aerosol is lead into an argon plasma. The solution to analyze is conducted by a peristaltic pump though a nebulizer into a spray chamber. The GI and the spin-off company B-WARE having two ICP-OES systems iCAP 6000 (Thermo Fischer Scientific, Bremen, Germany), and the high-end system ARCOS (Spectro Analytical, Kleve, Germany) Principle The technique has been commercially available since 1974 and thanks to its reliability, multi-element options and high throughput, it has become a widely applied in both routine research as in more specific analysis purposes. ICP-OES (Inductively coupled plasma - optical emission spectrometry) is a technique in which the composition of elements in (mostly water-dissolved) samples can be determined using plasma and a spectrometer. ![]()
