Infrared oil measuring instrument

Product Introduction:

The HM-CY1 infrared oil analyzer is developed and manufactured in accordance with the Chinese environmental protection standards HJ637-2018 Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared Spectroscopy Method, HJ1051-2019 Soil Petroleum Determination - Infrared Spectroscopy Method, and HJ1077-2019 Fixed Pollution Source Exhaust Gas - Determination of Oil Fume and Oil Mist - Infrared Spectroscopy Method. This instrument is a specialized infrared spectroscopic analysis instrument mainly used to detect the determination of oil content in surface water, groundwater, industrial wastewater, soil, fixed pollution source exhaust gas, oil fume and oil mist.

Application scope:

Infrared oil meters can be widely used in water environment detection systems, sewage treatment plants, water companies, petrochemicals, university research institutes, hydrology and water conservancy, metallurgy and steel, biomedicine, agricultural environment monitoring, wool textile printing and dyeing, marine environment monitoring, papermaking, medicine, agricultural technology, marine transportation and other fields.

Product principle:

According to the HJ637-2018 standard, the HM-CY1 infrared oil analyzer extracts oil substances from water with tetrachloroethylene to determine the total extract. Then, the extraction solution is adsorbed with magnesium silicate, and after removing animal and vegetable oils, the oil is determined. The total extract and petroleum content were calculated based on the absorbance A2930, A2960, and A3030 at the wavelength 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 hydrocarbons), respectively. The content of animal and vegetable oils is calculated based on the difference between the total extract and petroleum content.
