Chongqing fully automatic infrared oil analyzerProduct Overview: Compliant with the National Environmental Protection Standard of the People's Republic of China "HJ637-2012" for the determination of water quality, petroleum, and animal and vegetable oils using infrared spectrophotometry.
Chongqing fully automatic infrared oil analyzerTechnical principle:According to HJ637-2012 standard, extract oil substances in the sample with carbon tetrachloride, determine total oil, and then adsorb the extract with magnesium silicate to remove polar substances such as animal and vegetable oils before determining petroleum. The content of total oil and petroleum is calculated based on the absorbance A2930, A2960, and A3030 at spectral bands with wave numbers of 2930cm-1 (stretching vibration of C-H bond in CH2 group), 2960cm-1 (stretching vibration of C-H bond in CH3 group), and 3030cm-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.

Product features: The detachable integrated optical system makes the instrument small in size, short in optical path length, and high in energy. It first separates and then absorbs, meeting the requirements of infrared spectroscopy, with good stability and high signal-to-noise ratio.

Adopting advanced switch mode power source not only reduces the heat generation intensity of the light source to facilitate system heat dissipation, but also simplifies the instrument structure and improves instrument reliability by reducing mechanical cutting motion components.
Non expert maintenance, the optical and electrical systems of the instrument are self-contained and highly integrated, thereby improving the reliability and maintainability of the instrument.
Real time automatic zero adjustment, the computer collects both the signal when the light source emits light and the signal when the light source goes off, achieving real-time automatic zero adjustment, simplifying operation and improving long-term signal stability.
High analysis efficiency, the instrument can complete the analysis and determination of a sample within 30 seconds (2 seconds for non dispersive infrared method).
