Meet the standard
Meet the national standard: "HJ637-2018 Water quality of petroleum and animal and plant oils determination by infrared photometry"
HJ1077-2019 Determination of exhaust fumes and oil mist from stationary pollution sources - Infrared spectrophotometric method
HJ-1051-2019 Determination of petroleum in soil by infrared spectrophotometry
GB/T12152-2007 Determination of oil content in boiler water and cooling water
IRO-300plus Automatic Infrared Spectrophotometer Spectroscopic Oil Meter Oil Content Analyzer
Technical principle
According to the HJ637-2018 national standard, the oil substances in the water are extracted automatically with the magnetic stirring of tetrachloroethylene, and then the oil-water separation membrane is used instead of sodium sulfate to isolate impurities and water, separate the solution of oil and tetrachloroethylene, and determine the oil content of the total extract. At the same time, polar substances such as animal and plant oil were removed by adsorption of magnesium silicate, and petroleum types were determined. The total extract and petroleum contents were calculated by the absorbance A2930, A2960 and A3030 at the bands of 2930cm-1 (stretching vibration of C-H bonds in CH2 groups), 2960cm-1 (stretching vibration of C-H bonds in CH3 groups) and 3030cm-1 (stretching vibration of C-H bonds in aromatic rings), respectively It's OK.

IRO-300plus Automatic Infrared Spectrophotometer Spectroscopic Oil Meter Oil Content Analyzer
instrument application range
The instrument is mainly used to measure the oil content in domestic sewage and industrial wastewater. At the same time, it can also measure the content of oil in surface water and groundwater.5. Working structure principle
The automatic infrared oil detector is composed of automatic operating software system, infrared spectroscopy system and pre-treatment extraction system. The machine uses the three-dimensional stirring technology to extract the oil in the water, remove the water and impurities into the colorimetric dish and then measure. The built-in magnesium silicate adsorption device can measure the content of petroleum and animal and vegetable oils. After measuring, the instrument is automatically discharged and cleaned. Full automation, without operator contact with tetrachloroethylene, that is, automatic sampling, automatic extraction, automatic removal of water and impurities, automatic measurement, automatic cleaning, automatic drainage and storage of data.
