Qikun Technology CD-800SE Total Organic Carbon Analyzer

Qikun Technology CD-800SE Total Organic Carbon AnalyzerIt adopts high-temperature catalytic oxidation-NDIRDetection principle, an analytical instrument used to determine the total organic carbon concentration in water samples, capable of detectingTOCConcentration from 0ppmarrive35000.0ppmThe water sample has high sensitivity and accuracy And good stability.

principle

By using high-performance oxidation catalysts in the combustion furnace, the sample is fully burned and decomposed into carbon dioxide and water at high temperatures. The water vapor is removed after cooling by a condenser, and the carbon dioxide is detected by a non dispersive infrared detector（NDIR）Determine the total organic carbon content in the sample through measurement; Inorganic carbon in the sample is decomposed into carbon dioxide and water using an acid reagent. Water vapor is removed by cooling with a condenser, and carbon dioxide is detected using a non dispersive infrared detector（NDIR）Measurement to determine the total inorganic carbon in the sampleTICThe content; total organic carbonTOC=TC-TIC.
