Introduction

CU-500 TOC analysis module uses the static UV oxidation-Conductivity Detection. Deionized water samples for the determination of total organic carbon concentration of analytical instruments. TOC concentrations can be detected from 0.1ppb to 1000.0 ppb water samples with high sensitivity and accuracy, as well as good stability.

Application

Can be used for online monitoring the pharmaceutical industry Water system.
Ultra-pure water preparation system in the semiconductor industry, and the deionized water preparation process in power plants.

Fundamentals

Using UV light oxidation of carbon in water samples, After changes in the conductivity before and after oxidation of the sample to obtain the corresponding TOC values. During the test, water samples were isolated alone in a closed space, thus preventing contact with the surrounding environment pollution caused. The TOC value is through changes in the conductivity of the water samples before and after oxidation by UV light. To obtain the corresponding operations. The conductivity of the water sample is directly related to the content of organic carbon in water samples, and organic carbon content and can be completely oxidized to CO2 and measured.
