    CHF-1900 infrared spectrophotometer
    Introduction
    CHF-1900 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. This instrument is a professional instrument for measuring the oil content in water, gas and solids.
    According to the HJ637-2012 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
    1. In line with the national standard HJ637-2012, 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;
    2. Detachable integrated optical system, small size, short optical path, high energy, first absorbed after light splitting, good stability;
    3. The instrument workstation adopts the latest stable Microsoft .NET running platform, and the green hard disk version can be used without installation.
    4. Controlled by Windows 7 or Windows 10 operating system;
    5. Can be upgraded to a fully automatic infrared spectrophotometer to avoid contact with carbon tetrachloride;
    6. Can use tetrachloroethylene, other non-hydrocarbon organic solvents as extractants, manufacturers provide solvents, technical support, etc.;
    7. It can automatically adjust the wavelength position of the methylene 2930cm-1 of the instrument to achieve accurate measurement of the instrument.
    8. 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;
    9. Zero-point real-time adjustment, using pyroelectric infrared detector to accurately collect the pyroelectric signal formed when the halogen lamp is turned on;
    10. With automatic statistical analysis, spectrum display, storage, printing and other functions, wireless network remote control operation;
    11. It can detect the total oil, petroleum, animal and vegetable oil in the water sample, and also detect the oil in the oil smoke gas of the catering industry, and the oil in the solid;
    12. With the measurement instrument correction coefficient function;
    13. Can test the light transmittance and purity of the extraction solvent and distinguish various interferences.
    14. Electrically modulated light source, instead of mechanical switching of the light source, to improve the reliability of the instrument;
    15. The correlation coefficient is good, measuring 0.5-5 mg\L, R>0.999;
