Online/ Offline TOC with Conductivity Sensor
This instrument uses the classical flow-through concept for online or offline TOC monitoring of pure and ultra-pure water. The efficient UV oxidation of organic compounds by the “direct surface” principle in combination with conductivity detection guarantees the fast monitoring of values.
Online/ Offline TOC with NDIR Detector
This device uses the full oxidation by UV. The oxidation process can be enhanced with additional dosage of reagent (persulfate). The non dispersive infrared (NDIR) detector is absolutely selective to carbon dioxide and therefore independent from conductivity and sample temperature. In a first step the TIC (total inorganic carbon) is removed with carbon dioxide free stripped gas and after that value is measured. By using this NDIR detector, it gives precise results in applications of ground water to ultrapure water.
