A Dissolved Oxygen Analyzer with an Optical Sensor

A serial analyzer of dissolved oxygen, Expert-009, based on the optical detection method is created. The sensitive element of the sensor is a polymer film with a dye—a metal complex of fluorine-substituted porphyrin—distributed in it. The method is based on the quenching of the phosphorescence of th...

Description
Summary:A serial analyzer of dissolved oxygen, Expert-009, based on the optical detection method is created. The sensitive element of the sensor is a polymer film with a dye—a metal complex of fluorine-substituted porphyrin—distributed in it. The method is based on the quenching of the phosphorescence of the dye by molecular oxygen, which the analyzer recounts to the concentration value by the calibration curve method. The metrological characteristics of the analyzer are determined.
