Laboratory research.

MAIN FEATURES

Main features of Online Total Organic Carbon Analyzer TOCG-3040

Three detection modes: TC, TIC, TOC, NPOC, carried out in the same reactor.

Highly reflective gold-plated gas chamber, highly concentrated infrared light source and highly sensitive infrared detector ensure excellent performance of NDIR; the data at the ppb level has sufficient sensitivity and accuracy.

Precision metering pump to ensure the precision of the injection volume.

Double-pass electronic condensation dehydration technology.

Real-time visible detection curve, more intuitive.

Real-time self-monitoring function of multiple temperature, pressure and flow.

The curve can be formulated to meet the measurement of any water sample.

Working principle

TOCG-3040 total organic carbon analyzer adopts the principle of ultraviolet persulfate oxidation-NDIR detection. One sample was decomposed into CO2 by UV and persulfate oxidation, and the other sample was decomposed into CO2 by acid reagent. CO2 is dried and purified under the action of a carrier gas, and then enters a non-dispersive infrared detector (NDIR) to be measured so as to determine the carbon concentration in the sample.
