Portable infrared spectrophotometer EP910

Product Details

1Compliant with standards
comply with national standards“HJ 970-2018Water quality - Determination of petroleum - Ultraviolet spectrophotometric method
2Technical principles
atPH≤2 Under certain conditions, the oil substances in the sample were extracted with n-hexane. The extract was dehydrated with anhydrous sodium sulfate and then adsorbed with magnesium silicate to remove acute substances such as animal and plant oils225nmMeasure the absorbance at the wavelength, and the petroleum content and absorbance value are in accordance with Lambert-Beer’s law.
3Department using the instrument
environmental monitoring systemUsed in testing laboratories and laboratories for petrochemical, hydrological and water conservancy, water supply companies, sewage treatment plants, thermal power plants, steel enterprises, university research and teaching, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, marine environmental monitoring, transportation environmental monitoring, environmental research, etc.
4Scope of Instrument Application
This instrument is mainly used for the determination of petroleum in surface water, groundwater, and seawater.
