CHF-4500T automatic infrared spectrophotometer Introduction
CHF-4500T automatic infrared oil measuring instrument is composed of automatic operation software, infrared spectroscopic system and magnetic stirring extraction system. Using extraction solvent (CCl4 or C2Cl4) according to a certain extraction ratio, the oil in the water body is adopted by the drum type stereo stirring technology. The extract is extracted, and the extraction solution is introduced into the cuvette by removing water and removing impurities through a filtering device, and is analyzed and measured by the infrared spectroscopic system. A special magnesium silicate filter unit can be added to measure the content of petroleum and animal and vegetable oils. After the measurement is completed, the instrument automatically drains the cleaning pipeline. The whole process is automated, without the need for operators to contact carbon tetrachloride, ie automatic injection, automatic extraction, automatic water removal and impurity removal, automatic measurement, automatic cleaning, automatic drainage and storage of data.
CHF-4500T automatic infrared oil detector is mainly used for the measurement of oil content in surface water, groundwater and industrial wastewater. Features
1. Fully automated: fully automatic injection, extraction, water filtration, measurement, drainage, cleaning, continuous 8-10 water samples;
2, health and safety: extraction and other operations without the participation of analysts, and contact with carbon tetrachloride, to ensure the health and safety of operators;
3. The extraction method conforms to the national standard HJ637-2012, and the extraction results are consistent with the results of the national standard method.
4, has the core technology: the configuration of imported oil and water separation membrane filtration, instead of anhydrous sodium sulfate in addition to water and impurities, a film can be used about 100 times.
5, can use tetrachloroethylene and other reagents for automatic extraction detection, instead of the more toxic carbon tetrachloride solution, the manufacturer provides standard solvent, technical support, etc.;
6, built-in touch computer terminal, can also be connected to a desktop computer, with intelligent processing information, storage, print and save functions;
7. Adopting the most efficient drum stereo magnetic stirring extraction technology, the extraction efficiency is higher than 95%
8, using Windows7 or Windows10 operating system control.
9. Adopt the most stable and mature .NET4.0 platform green free installation oil meter software;
10, the true three-wavenumber, the infrared three-wavenumber spectrum is clear, the scale is accurate, and the absorption spectrum and absorbance generated by the three wave numbers can be clearly displayed.
11. Built-in magnesium silicate adsorption column can measure mineral oil, animal and vegetable oil, and can be upgraded to online monitor by adding automatic sampler;
12, one-button calibration: blank and standard oil sample automatic detection automatic correction;
13. One-click completion: Adjusting the blank and adding multiple water samples can be completed with one click, reducing the workload of the operator;
14. The whole extraction system adopts anti-acid and alkali-proof carbon tetrachloride, full anti-corrosion and non-oil-friendly materials, runs the cleaning process, and reduces high and low concentration cross-contamination;
15. Automatic dilution and enrichment: the dilution enrichment ratio can be set arbitrarily;
16. Automatically separate water and carbon tetrachloride waste liquid, and automatically collect waste water and other reagents such as carbon tetrachloride to discharge waste water;
