Overview

The fully automatic infrared photometric oil analyzer is designed and manufactured in accordance with the requirements specified in HJ637-2018 "Determination of Water Quality, Petroleum, Animal and Plant Oils by Infrared Spectrophotometry". Mainly used in environmental monitoring departments and production departments for the determination of petroleum and animal and plant oils in industrial wastewater, domestic sewage, and soil. At the same time, it also measures the concentration of cooking oil fume emissions in the catering industry according to the national cooking oil fume emission standard (GB18483). Main application areas: environmental monitoring stations, determination of domestic and industrial wastewater; Food and beverage industry oil fume monitoring units; Municipal drainage monitoring station, sewage treatment plant; Petroleum and petrochemical enterprises; railway

Product Details

principle

Extract oil substances from water using tetrachloroethylene, determine the total extract, and then adsorb the extract with magnesium silicate. After removing polar substances such as animal and vegetable oils, determine petroleum. The total extract and petroleum content were calculated based on the absorbance A2930, A2960, and A3030 at spectral bands with wave numbers of 2930 cm-1 (stretching vibration of C-H bond in CH2 group), 2960 cm-1 (stretching vibration of C-H bond in CH3 group), and 3030 cm-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.

Features

Chinese menu operation, no need for sample calibration, can be used alone, with stable functions such as mathematical statistics, spectrum display, storage, printing, etc. Automatic switching mechanism between sample and reference cell, precise positioning, error elimination, stable measurement effect, and automatic zero adjustment. Adopting an integrated optical path system, optical path design, strong signal, and high signal-to-noise ratio. Real time automatic zeroing. The instrument collects signals separately when the light source flashes off, achieving real-time automatic adjustment of zero point, simplifying operation, and ensuring the stability of the instrument's long-term operation

In accordance with the requirements of the national standard HJ637-2018, infrared spectrophotometry does not require a standard curve, only a set of correction coefficients for precise positioning. Using the residual cut method for precise wavenumber positioning scanning, ensuring that the wavenumber positioning accuracy is less than one wavenumber. Efficient optical/electrical system design. By using a pulse light source, the heat generation intensity of the light source is effectively reduced, which is beneficial for system heat dissipation and improves instrument reliability and component lifespan. Pre integrated narrowband active filter and digital lock-in amplifier significantly improve signal-to-noise ratio and stabilize performance
