Working principle

　　CW-700S Total Organic Carbon AnalyzerAdopting the principle of UV persulfate oxidation NDIR detection. One sample is fully oxidized and decomposed into CO2 through UV and persulfate, while the other sample is decomposed into CO2 through acid reagents. Under the action of a carrier gas, CO2 is dried and purified before entering a non dispersive infrared detector (NDIR) for determination of carbon concentration in the sample.
