IRO-200 infrared spectrophotometer Introduction
IRO-200 infrared spectrophotometer is mainly used for the measurement of oil content in surface water, groundwater and industrial wastewater. It can also be used for monitoring the oil in the flue gas of the catering industry and monitoring the oil content in the solid. 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
◇In line with national standard HJ637-2018, the infrared three-wavenumber spectrum is clear, the scale is accurate, and the absorption spectrum and absorbance generated by three wave numbers can be clearly displayed;
◇ detachable integrated optical system, small size, short optical path, high energy, first absorbed after light splitting, good stability;
◇The instrument workstation adopts the latest stable Microsoft .NET running platform, and the green hard disk version can be used without installation;
控制Controlled by Windows 7 or Windows 10 operating system;
◇ can be upgraded to a fully automatic infrared spectrophotometer;
◇Using tetrachloroethylene as extractant, the manufacturer provides solvent, technical support, etc.;
◇Automatically adjust the wavelength position of the methylene 2930cm-1 of the instrument to achieve accurate measurement of the instrument.
◇The instrument has a built-in touch tablet, an external wireless mouse and keyboard, and an external computer, which is convenient and quick to operate;
◇ Zero-point real-time adjustment, using pyroelectric infrared detector to accurately collect the pyroelectric signal formed when the halogen lamp is turned on;
◇ With automatic statistical analysis, spectrum display, storage, printing and other functions, wireless network remote control operation;
◇ can detect the total oil, petroleum, animal and vegetable oil in the water sample, and also detect the oil in the cooking gas of the catering industry, and the oil in the solid;
◇ has the function of measuring instrument correction coefficient;
◇ can test the light transmittance and purity of the extraction solvent and distinguish various interferences.
◇Electrical modulation light source, instead of mechanical switching of light source, improve instrument reliability;
