Product Details
| Brand Name: | QIKUN | Place of Origin: | Shaanxi, China | Model Number: | CW-700S |
Product Description
The CW-700S is a compact instrument. The main components are installed on the mainframe. Before the measurement, the instrument needs to connect the gas path and prepare reagents. The instrument is controlled by specialized software installed on an external computer for data processing such as measurement, calibration, and printing. How it works: The principle of UV-persulphate oxidation-NDIR detection is used. One sample was fully oxidized and decomposed to CO2 by UV and persulfate, and the other sample was decomposed by inorganic reagents to CO2. CO2 is dried and decontaminated by a carrier gas and then passed into a non-dispersive infrared detector (NDIR) to determine the concentration of carbon in the sample.
Features:
1 Meet the requirements of the EP, USP, and 2015 editions of the Chinese Pharmacopoeia;
2 three detection modes: TC, TIC, TOC, NPOC, carried out in the same reactor;
3 High-reflective gold-plated gas chamber, high-concentration infrared light source and high-sensitivity infrared detectors ensure excellent performance of the NDIR. 4 Measurement of ppb-level data has sufficient sensitivity and accuracy.
5 precision electromagnetic metering pumps, to ensure the accuracy and stability of the injection volume;
6 dual-tube electronic condensation dehydration technology;
7 Detection curve can be seen in real time, more intuitive;
8 multiple real-time self-monitoring functions for temperature, pressure and flow;
9 It is possible to formulate curves according to the range and meet the measurement of any water sample;
10 optional online module for online monitoring;
11 Optional auto sampler, unattended, saving manpower and time.
