DEVICE FOR SPECTROPHOTOMETRIC MONITORING NATURAL WATER Russian patent published in 2010 - IPC G01N21/27 

FIELD: physics.

SUBSTANCE: spectrophotometre sensor is made in form of a inductor with a flow channel on whose sides of which there is a photosource and a photodetector connected to the electrical circuit of the spectroelectrophotometre. Providing the sensor with a flow channel enables its use to monitor natural water bodies using river vessels in any place and at any depth. The alternating current inductor excites secondary electric currents in the water, thereby carrying out electrolysis of the aquatic medium, which transforms all impurities in the aquatic medium into an excited state, thereby increasing intensity of absorption spectra of all components. For operation, the detachable induction pick up of the spectrophotometre is taken overboard the river vessel, whose cabin laboratory is fitted with a spectrophotometre and an onboard power supply.

EFFECT: possibility of monitoring aquatic medium at low concentrations.
