IRO-100 infrared spectrophotometer Introduction
IRO-100 infrared spectrophotometer is mainly used for the measurement of oil content in surface water, groundwater and industrial wastewater. It can also be used for the monitoring of oil in flue gas in the catering industry and the monitoring of oil content in solids. The instrument is a professional instrument for measuring the oil content in water, gas and solids.
According to the HJ637-2018 standard, the oily substance in the water is extracted with carbon tetrachloride, the total extract is measured, and then the extract is adsorbed with magnesium silicate, and after removing polar substances such as animal and vegetable oil, petroleum is measured. The total extract and petroleum content are all from the wave number of 2930 cm-1 (the stretching vibration of the CH bond in the CH2 group), 2960 cm-1 (the stretching vibration of the CH bond in the CH3 group), and 3030 cm-1 (in the aromatic ring). The stretching vibration of the CH bond) The absorbances at the bands A2930, A2960, and A3030 were calculated. The content of animal and vegetable oils is calculated as the difference between the total extract and petroleum content. Feature
◇The true three-wavenumber, the infrared three-wavenumber spectrum is clear, the scale is accurate, and the absorption spectrum and absorbance generated by the three wave numbers can be clearly displayed;
◇ has the function of measuring instrument correction coefficient;
◇ can test the light transmittance and purity of the extractant, and can distinguish various interferences;
◇Using a dedicated NC infrared light source, it has a long life and no other light;
◇Electrical modulation light source instead of mechanical switching light source, simplifying structure and improving performance;
The heat release sensitive photoelectric detector collects the double signal when the light source is turned off, and realizes the automatic adjustment of the zero point of the infrared light from time to time;
◇Controlled by Windows XP or win7 operating system;
◇ using other non-hydrocarbon organic solvents such as tetrachloroethylene and trichlorotrifluoroethane as extractants;
◇ With automatic statistical analysis, spectrum display, storage, printing and other functions.
◇Removable integrated optical system, small size, short optical path, high energy, first absorption after absorption, good stability. Technical parameter
