Description of the systems
The analysis method of optical emission spectrometry (OES) with inductively coupled plasma makes use of the fact that excited atoms and ions emit electromagnetic radiation, the radiation intensity of which can be used for the quantitative detection of elements. For this purpose, the elements must be transferred from their compounds to the excited state, which takes place by introducing the sample solution into a plasma. During the transition to the ground state, the excited electrons of the elements emit element-specific radiation in the form of electromagnetic waves. The wavelengths of the emitted light are determined using a calibrated scale, whereby the measurement is carried out with a photoelectric detector. The advantages are the high sensitivity (0.02 - 50 µg/L) with good precision (RSD < 1 %) and short analysis times.
