Infrared spectrometer / oil-in-water

Meeting the standard: PRC 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.

Main technical index:
1. Detection limit: 0.04mg/L (calculate 3 times standard deviation measuring 11 times blank)
2. Wavelength Range: 3400cm-1?2400cm-1(2941nm?4167nm)
3. Absorbency range: 0.0000?2.0000AU (transmittance 100?1%T)
4. Minimum detectable concentration: 0.001mg/L (enrichment extraction method)
5. Maximum measured concentration: 10000mg/L (dilution gaging)
6. Instrument measurement range: ?0.05?100?mg/L
7. Repeatability: RSD?1% (20-100mg/L Oil sample determined 11 times)
8.Measurement accuracy: error 0.999
10. Main machine net weight: 13kg
11.Main machine external dimension: 450mm×350mm×130mm
