FIELD: process engineering.SUBSTANCE: proposed method comprises initiation of local electric discharge in analysed fluid to form current conducting channel in volume of diaphragm orifice made in structural element of electrolytic cell and registration of emission spectra originating hereat of chemical elements under analysis. Note here that, first, elements under analysis are deposited in volume of current conducting channel at current insufficient for initiation of local electric discharge. Then, current direction is reversed to increase its magnitude for initiation of local electric discharge. Radiation originated in analysed fluid is registered to obtain emission spectra of analysed chemical elements.EFFECT: stable and reproducible measurement results, longer life.2 cl, 3 dwg |
