FIELD: analytical chemistry.
SUBSTANCE: sensor can be used for inspecting level of oxidants and antioxidants in liquid. Device for detecting absence or presence of reduction-oxidation reactive-capable analyzed matter in water sample has electro-chemical cell with sensor chamber, first and second electrodes, hole for introducing sample into sensor chamber and reagent placed inside sensor chamber. Electro-chemical cell is designed to be removable after usage in any unique experiment. Reagent is capable of subjecting to reduction-oxidation reaction directly with analyzed matter to generate electric signal indicating absence or presence of analyzed matter. Method of detecting level of reduction-oxidation reaction-capable matter is also proposed as well as method of measurement of sulfur dioxide in sample of vine and method of producing device mentioned before.
EFFECT: improved precision.
