CW-700 Total Organic Carbon Analyzer Introduction
CW-700 total organic carbon analyzer is an analytical instrument independently developed by Hangzhou Qiye Technology Co., Ltd. for measuring the total organic carbon concentration in water samples. It can detect water samples with TOC concentrations from 0.001 mg / L to 100.0 mg / L. , With high sensitivity and accuracy, and good stability.
CW-700 type total organic carbon analyzer adopts UV persulfate oxidation-NDIR detection principle.
Subtraction
The sample is fully oxidized and decomposed into carbon dioxide and water by ultraviolet persulfate. After condensation and dehydration, the carbon dioxide is measured by a non-dispersive infrared detector (NDIR) to determine the total carbon TC content in the sample; the inorganic carbon in the sample is decomposed by an acid reagent Carbon dioxide and water are formed. After condensation and dehydration, carbon dioxide is measured with a non-dispersive infrared detector (NDIR) to determine the content of total inorganic carbon TIC in the sample. Total organic carbon TOC = TC-TIC.
Direct method
Firstly, the inorganic carbon in the sample is decomposed into carbon dioxide and water by acid reagent, and the total inorganic carbon TIC is removed. Then, the organic carbon in the sample is decomposed into carbon dioxide and water by ultraviolet persulfate. (NDIR) determination to determine the content of TOC in the sample.
Features
1. 7-inch touch screen, user-friendly interface, simple and convenient operation
2. Three detection modes: TC, TIC, TOC, NPOC, performed in the same reactor
3. High-reflective gold-plated gas chamber, high-concentration infrared light source and high-sensitivity infrared detector ensure excellent performance of NDIR; the ppb-level data has sufficient sensitivity and accuracy
4. Dual-pipe pass electronic condensation dehydration technology
5. The detection curve is visible in real time, which is more intuitive
6. Precise electromagnetic metering pump to ensure the accuracy and stability of the injection volume
7. Multiple temperature, pressure and flow real-time self-monitoring functions
8. Built-in dot-matrix printer to reduce space
9. 2 years of data storage, easy to query, and query by time period
10. With password protection
11. Suitable for high-salt samples and water samples with a high proportion of total inorganic carbon
12. Optional online module for online monitoring
13. Optional automatic sampler, unattended, saving manpower and time
14. Comply with the international standard ISO8245, the national environmental protection standard HJ501-2009 of the People's Republic of China, the national metrological verification regulations of the People's Republic of China JJG 821-2005 and the provisions of the Chinese Pharmacopoeia
