Automatic infrared oil analyzer for detecting oil concentration in water
Automatic infrared oil analyzer for detecting oil concentration in water
Product details
1EP4000B fully automatic infrared oil analyzerCompliant with standards
According to the national standard HJ637-2018, water quality - Determination of petroleum, animal and vegetable oils - Infrared spectrophotometric method
2. Technical principles
According to the HJ637-2018 national standard, fully automatic extraction of oil substances in water is carried out using magnetic stirring with tetrachloroethylene. Then, an oil-water separation membrane is used instead of anhydrous sodium sulfate to isolate impurities and moisture, separating the solution of oil and tetrachloroethylene, and determining the total oil content of the extract. At the same time, after adsorption and removal of polar substances such as animal and vegetable oils by magnesium silicate, petroleum products are determined. The total extract and petroleum content were calculated based on the absorbance A2930, A2960, and A3030 at spectral bands with wave numbers of 2930 cm-1 (stretching vibration of C-H bond in CH2 group), 2960 cm-1 (stretching vibration of C-H bond in CH3 group), and 3030 cm-1 (stretching vibration of C-H bond in aromatic ring), respectively.
3. Department using the instrument
Environmental monitoring systems are used in testing rooms and laboratories for petrochemical, hydrological and water conservancy, water supply companies, sewage treatment plants, thermal power plants, steel enterprises, scientific research and teaching in universities, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, marine environmental monitoring, transportation environmental monitoring, environmental research, etc.
4EP4000B fully automatic infrared oil analyzerApplication scope
This instrument is mainly used for measuring the oil content in domestic sewage and industrial wastewater. At the same time, it can also measure the content of petroleum in surface water and groundwater.
5. Working structure principle
EP4000B fully automatic infrared oil analyzerComposed of a fully automated operating software system, infrared spectroscopy system, and pre-processing extraction system. The machine adopts drum type three-dimensional mixing technology to extract oil from water, remove water and impurities, and then measure it in a colorimetric dish. The built-in magnesium silicate adsorption device can measure the content of petroleum and animal and vegetable oils. After the measurement is completed, the instrument will automatically discharge and clean the waste. Fully automated, without the need for operators to come into contact with tetrachloroethylene, including automatic sampling, extraction, water and impurity removal, measurement, cleaning, drainage, and data storage.
