0 ~ 1000mg / L Total Organic Carbon Analyzer
CHL-TOC1000M
Introduction
CHL-TOC1000M Total Organic Carbon Analyzer applies 680 ℃ catalytic combustion oxidation technique. It imports the sample together with the cleaned gas (high purity oxygen) to the high temperature combustion tube and low temperature reaction tube. After going through the high temperature combustion tube, the organic carbon and inorganic carbon among the sample are converted into carbon dioxide by high-temperature catalytic oxidation,and after going through the low temperature reaction tube, the inorganic carbon among the sample is converted into carbon dioxide by acidification. Both kinds of carbon dioxide produced in the reaction tube are imported into non-dispersive infrared gas detector NDIR sequentially, where the CO2 will be detected. Thus the total carbon (TC) and inorganic carbon (IC) contained in the water can be measured. The total organic carbon (TOC) is equal to total carbon minus the inorganic carbon. This instrument is mainly used by pharmaceutical companies in cleaning validation and measuring the
organic matters of surface water, groundwater, sewage, industrial waste water, tap water, purified water, etc.
Features
1. A data terminal can be configured at most eight detection units so that the analyzer can detect eight points simultaneously.
2. It realized the function of online multi-point, continuous testing on the water supply system ; which is cost-effective , ease to operate, and can reduce the workload.
3. 8 monitoring points data are displaying together, and can be centralized-controlled; and it displays TOC, conductivity and temperature values at the same time.
4. Analysis interval time and data storage interval can be set arbitrarily .
5. With automatic limit alarm output function, it reminds the operator timely when data anomalies.
6. With deadline countdown function of the UV light, it calculates the UV lamp usage time accurately.
7. Data can be stored and for reference , and it can save more than 5 years’ data.
8. With USB interface, can export data through the U disk.
9. A print output.
10. Detection mode can be switched off for testing, calibration and validation.
11. Without adding acid reagent, oxidants, and any gas, no additional maintenance fees.
12. It is simple, fast, and reliable to operate, and users do not need expertise and specialized training.
13. Small size, light weight, low energy consumption.
14. With water splash preventing design, it can work in wet and high temperatures conditions.
15. Compact cabinet designed to meet the demanding requirements of the industrial environment.
16. Easy to do the system suitability test that follows USP <643> and EP <2.2.44> and the Chinese Pharmacopoeia Appendix
