Inductively Coupled Plasma - Optical Emission Spectrometer

The monochromatic light of a mercury vapour lamp is used to excite electrons in the shells of ions. Relaxation emits light of element-characteristic wavelengths measured by a semiconductor detector.

Concentrations of elements are measured in filtered and acidified samples in the range from 10 µg/L to 100 000 µg/L, but best between 100 µg/L and 10 000 µg/L. Ag, Al, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, In, K, Li, Mg, Mn, Na, Ni, Pb, Sr, Tl and Zn are usually measured within a calibration range from 10 µg/L to 40 000 µg/L.
