Infrared oil analyzer meets the standard
Meets the national standard "HJ637-2012 Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared Photometric Method"Third party detection use of infrared oil analyzer
Infrared oil analyzerTechnical principle:
According to the HJ637-2012 standard, extract oil substances from water using carbon tetrachloride, determine the total extract, and then adsorb the extract with magnesium silicate. After removing polar substances such as animal and vegetable oils, determine petroleum. The total extract and petroleum content were calculated based on the absorbance A2930, A2960, and A3030 at spectral bands with wave numbers of 2930 cm-1 (stretching vibration of C-H bond in CH2 group), 2960 cm-1 (stretching vibration of C-H bond in CH3 group), and 3030 cm-1 (stretching vibration of C-H bond in aromatic ring), respectively. The content of animal and vegetable oils is calculated based on the difference between the total extract and petroleum content.
