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 enables accurate TOC measurement by using a "gas permeable membrane module," which separates carbon dioxide from the sample water to the pure water line within the analyzer through a thin Teflon film, thereby eliminating the influence of other ions.
