Product Details

Working Principle

The TOC-600OS-OL Total Organic Carbon Analyzer uses a UV lamp to oxidize slowly flowing water samples. The TOC value of the sample is obtained by measuring the change in conductivity before and after oxidation.
Under the action of a peristaltic pump, the water sample enters a PTFE tubing line, passing sequentially through the first electrode, the quartz spiral tube, and the second electrode, before finally being discharged through the waste tube.
During detection, conductivity values from both sensors (G1 and G2) are simultaneously recorded. Organic matter in the sample is oxidized by dual UV lamps to produce CO₂, which increases conductivity. The corresponding TOC is derived from the difference (G2 – G1).

Applications

Online TOC monitoring of water systems in the pharmaceutical industry;
Online monitoring of ultra-pure water preparation systems and wafer process lines in the semiconductor industry;
Online monitoring of deionized water preparation processes in power plants.
