Applications
On line monitoring and laboratory testing of pharmaceutical water (purified water, injection water), and cleaning validation; Environmental testing, electronic industry, food industry, etc.
Main features:
1. A large number of technological upgrading on the basis of TOC-10, which have no pump pipe and no need to configure the valve device online testing.
2. The new high performance CPU processor improves the processing speed and precision.
3. The instrument can save 500 records.
4. No pump pipe design, which not only reducing consumables, but also simplifying the installation procedure, and make flow rate more stable.
5.With automatic alarm function, when the data is abnormal, it will remind;
6. Color touch screen, user-friendly interface, easy to control;
7.No need to add acid reagent, oxidizing agent and carrier gas, so it can reduce the cost of daily use.
8.On-line and off-line test of two modes can be free to switch, it is convenient to use in different occasions.
9. Fully meet the “Chinese Pharmacopoeia”, USP < 643 > and < 2.2.44 > EP on system suitability test, simple and reliable operation;
10.Independent R&D team, can design various specific programs according to the needs of customers.
Operation principle
oxidation organism by UV lamp and convert organic stuff into carbon dioxide, which detection adopted by direct conductivity method. The total organic carbon is the difference of the total carbon (TC)concentration in samples tested after oxidation and not oxidation of the sample total inorganic carbon(TIC), namely: TOC = TC- (TIC).
