水中总有机碳分析仪
TOC (Total organic carbon) Analyzer

 

 

 

 

水中总有机碳分析仪

GV-1000

    工作原理是:样品中的有机物在紫外线(UV)的作用下被氧化成二氧化碳,二氧化碳的测定采用了电导率检测技术。通过测定未经氧化的样品的总无机碳(TIC或IC)浓度,和经氧化后得到的样品的总碳(TC)浓度来计算总有机碳浓度。总有机碳浓度即总碳浓度与总无机碳浓度之间的差值:TOC = TC–TIC。

    符合《美国药典》、《欧洲药典》以及《中国药典》最新的要求,可广泛应用于超纯水、制药用水、饮用水、生物化工产品等的有机碳含量的测定。

    本产品检测TOC浓度从0.001mg/L到1.000mg/L的水样。操作简单,维护费用低,无需添加化学试剂,操作人员无需特殊培训或专业化学知识。

TOC(Total organic carbon)ANALYZER
GV-1000

 

Description
GV-1000 TOC analyzer is a high performance testing analysis instrument, with independent intellectual property rights. It can detect total organic carbon (TOC) contain in the testing water, by calculating it from total inorganic carbon (TIC) and total carbon (TC). GV-1000 analyzer operation principle is to oxidize microorganism by UV lamp and convert organic stuff into carbon dioxide. It adopts dual wavelength ultraviolet nano-catalytic oxidation method, with its oxidation capacity increased over 100 times than traditional single-wavelength ultraviolet oxidation.
It can detect the ultrapure water which the TOC content is only 1μg/L, also can detect sample water which the TOC content reaches 1000μg/L.

This equipment is easy to operate, low maintenance, no need to add chemical reagent, and no need supply special training or professional chemical knowledge for operator.

It meets the latest requirements of "United States Pharmacopoeia", "European Pharmacopoeia" and "Chinese Pharmacopoeia", and it can be widely used to measure the organic carbon contained in ultra-pure, pharmaceutical water, drinking water, bio-chemical products, etc.
