Detailed information
-
- Sievers' unique gas permeable membrane conductivity measurement method In the TOC measurement method for conductivity, the conductivity indicated by the carbon dioxide (carbonate ions) generated after the oxidation and decomposition of organic matter is measured to calculate the carbon concentration. The Sievers M500e employs a "gas permeable membrane module," which uses a thin Teflon film to separate carbon dioxide from the sample water into the pure water line within the analyzer, enabling accurate TOC measurements by eliminating the influence of other ions.
