Infrared photometric oil analyzer

The infrared spectrophotometric oil analyzer is developed and manufactured in accordance with Chinese environmental protection standards HJ637-2018 “Determination of Petroleum Hydrocarbons and Animal/Vegetable Oils in Water by Infrared Spectrophotometry,” HJ1051-2019 “Determination of Petroleum Hydrocarbons in Soil by Infrared Spectrophotometry,” and “HJ1077-2019 Determination of Oil Fumes and Oil Mist in Exhaust Gas from Fixed Pollution Sources—Infrared Spectrophotometric Method.” This instrument is a specialized infrared spectroscopic analyzer designed for measuring oil content in surface water, groundwater, industrial wastewater, soil, exhaust gas from fixed pollution sources, oil fumes, and oil mist.

The infrared spectrophotometric oil analyzer can be widely applied in water environment monitoring systems, wastewater treatment plants, water supply companies, petrochemical industries, universities and research institutions, hydrology and water conservancy, metallurgy and steel, biopharmaceuticals, agricultural environmental monitoring, textile dyeing and printing, marine environmental monitoring, papermaking, pharmaceuticals, agricultural technology, and marine transportation sectors.

The infrared oil analyzer complies with the HJ637-2018 standard, using tetrachloroethylene to extract oil substances from water, determining the total extractable substances, then adsorbing the extract with magnesium silicate, removing animal and plant oils, and finally measuring the petroleum content. The concentrations of total extractables and petroleum hydrocarbons are determined by the wavenumbers 2930 cm⁻¹ (stretching vibration of the C-H bond in the CH₂ group), 2960 cm⁻¹ (stretching vibration of the C-H bond in the CH₃ group), and 3030 cm⁻¹ (stretching vibration of the C-H bond in aromatic hydrocarbons) are calculated using the absorbance values A2930, A2960, and A3030. The content of animal and vegetable oils is calculated as the difference between the total extractable substances and the petroleum hydrocarbon content.
