SED-60TOC-H — Analysator für gesamten organischen Kohlenstoff
Die vollständige Beschreibung dieses Modells wird noch übersetzt. Lesen Sie die englischen Details oder fragen Sie unser Team nach weiteren Informationen. English
SED-60TOC-H total organic carbon (TOC) analyzer for water samples. Measures TOC 0.1–1500 µg/L by UV-oxidation differential conductivity method (dual UV lamps + 2 conductivity electrodes). High sensitivity and precision;
Funktionsweise
Sample is delivered by peristaltic pump through Teflon tubing past conductivity electrode 1, then through a quartz spiral tube irradiated by dual UV lamps, then past electrode 2 to drain. Conductivity is recorded before (G1) and after (G2) UV oxidation; UV converts organic carbon to CO2 raising conductivity, and the differential (G2 − G1) yields the TOC value. Temperature compensation is applied to both conductivity measurements.
