HJ637-2018 Determination of petroleum and animal and vegetable oils Infrared spectrophotometry "HJ1077-2019 Determination of exhaust fumes and oil mist from fixed pollution sources Infrared spectrophotometry" instrument fully conforms to the "HJ 1051-2019 determination of petroleum in soil Infrared spectrophotometry GB5085.6-2007 Determination of the total amount of recoverable petroleum hydrocarbons in solid waste infrared spectroscopy and so on
2. IRO-100 infrared spectrophotometer technical principle:
According to the HJ637-2018 standard, the oil substances in the water are extracted with tetrachloroethylene, the total extract is determined, and then the extract is adsorbed with magnesium silicate, and after removing polar substances such as animal and plant oil, the petroleum is determined. The total extract and petroleum contents were calculated by the absorbance A2930, A2960 and A3030 at the bands of 2930cm-1 (stretching vibration of C-H bonds in CH2 groups), 2960cm-1 (stretching vibration of C-H bonds in CH3 groups) and 3030cm-1 (stretching vibration of C-H bonds in aromatic rings), respectively It's OK. The content of animal and vegetable oils is calculated as the difference between the total extract and the petroleum content.
3, the use of the instrument department
Environmental monitoring system, petrochemical industry, hydrology and water conservancy, tap water, sewage treatment plant, thermal power plant, iron and steel enterprises, scientific research and teaching in universities, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, Marine environmental monitoring, traffic environmental monitoring, environmental research and other testing rooms and laboratories.
4, instrument application range
The instrument is mainly used in the measurement of oil content in surface water, groundwater, industrial wastewater, and can also be used in the monitoring of oil in the flue gas of the catering industry and in solids
IRO-100 Infrared Oil Spectrophotometer NIR Spectrometer for Liquid Samples
Technical characteristics
1. The real three-wave number, infrared three-wave number spectrum is clear, the scale is accurate, and the absorption spectrum and absorbance generated by three wave numbers can be clearly displayed;
2. With measuring instrument correction coefficient function;
3. Can test the light transmittance and purity of the extractant, can distinguish various interference;
4. Use special NC infrared light source, long life, Wu other light irradiation;
5. Electrically modulated light source, replacing mechanical switching light source, simplifying structure and improving performance;
6. The thermoluminescent photodetector collects the double signal when the light source is on and off, and realizes the automatic adjustment of the zero point of infrared light;
7. Use Windows XP or win7 operating system control;
8. Other non-hydrocarbon organic solvents such as tetrachloroethylene and trichlorotrifluoroethane can be used as extractants;
9. With automatic statistical analysis, spectrum display, storage, printing and other functions.
10. Removable integrated optical system, small size, short optical path, large energy, first split-absorption, good stability.
