Meeting the standard: Conform to national standard“HJ637-2012 water quality the determination of petroleum and animal and plant oil Infrared photometric method”

 

Technical principle: According to HJ637-2012 standard, extract the oil material in the water using tetrachloromethane, measure the total extracts, extract liquor adsorb via adsorb magnesium silicate, after removing polar material such as the animal and plant oil, determine oil type. The total extracts and the content of petroleum are calculated by absorbance A2930,A2960 and A3030 in the spectrum band ,wave number 2930cm-1(stretching vibration of C-H key in CH2 group ), 2960cm-1(stretching vibration of C-H key in CH3group), 3030cm-1(stretching vibration of C-H key in aromatic nucleus ).The content of animal and plant oil are calculated by the difference of total extractor and oil content.

 

Using department of instrument:

Environment monitor system, petrochemical, hydrology and water conservancy, water supply company, sewage treatment works, thermal power plant, iron and steel enterprise, teaching and research work in university, agricultural environmental monitoring, Railway environmental monitoring, automobile making, marine environmental monitoring, transport environment monitoring, environmental scientific researches, inspection room, used in laboratory.

 
Instrument application range:

The equipment is mainly used in the measurement of oil content in the surface water, groundwater, industry waste water, which also can be used in the oil monitoring of smoke in catering industry and monitoring of oil content in the solid. This instrument is professional instrument to measure the oil content in water, gas, solid.
