FIELD: analytical control of molecular oxygen.
SUBSTANCE: method comprises the sampling of the heat carrier, throttling and cooling of the sample and measuring of the dissolved oxygen mass concentration with amperometric transducer. Additionally, the heat carrier flow rate in the pipeline and the pressure in the circuit and transducer are measured; the sample is throttled in the pipeline having inner diameter not more than 2 mm and length not less than the value determined according to the following formula.
EFFECT: increasing of the obtained results reliability and enhancement of the method usage field.
