Principle of Operation
Principle of analyzer operation is based on the excitation of emission radiation of atoms of chemical elements being under examination by means of local electric discharge in analized water with the subsequent recording and processing of radiation spectrum. Intensity of the emission radiation lines of any element is proportional to its concentration in analized water.
