Meet the requirements of TOC testing regulated by the Chinese Pharmcopoeia (2010 version) for pharmaceutical grade water
TOC-10 TOC tester is designed for the online and offline test of pharmaceutical grade water, WFI(water for inj.), ultra-pure water, and deionized water and etc. Based on the conductivity difference technology, it is being of high-precision capacity and short response-time, also meets the regulation standards issued by government.
Applications
Pharmaceutical water (purified water, water for injection) on-line monitoring and laboratory testing and cleaning validation;
Environmental testing, electronic industry, food industry and so on.
Working Principle
This tester adapts the UV-oxidation method,to oxide the sample organic contaminants into carbondioxide gasthoroughly which dissolve into liquid phase instantly,this will result the conductivity difference signal between test tube and control tube,and the final TOCvalue can be converted out by the below formula:TOC=TC(total carbon in test tube)- TIC(total inorganic carbon incontrol tube).
