Portable infrared spectrophotometer for oil analysis of animal and vegetable oils, petroleum products, and water-based oils

1、 Product IntroductionPortable infrared spectrophotometer for oil analysis of animal and vegetable oils, petroleum products, and water-based oils

The OIL 910B portable infrared oil analyzer adopts an integrated design, which is compact, easy to carry, and convenient for on-site use. It also complies with the national environmental protection standard of the People's Republic of China, HJ637-2018 Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared Luminescence MethodAnd《HJ1051-2019 Determination of Petroleum in Soil - Infrared Spectrometric Method.

2、 Technical principles

The OIL 910B portable infrared oil analyzer extracts oil substances from samples using tetrachloroethylene according to HJ637-2018 standard, determines total oil, and then adsorbs the extract with magnesium silicate to remove polar substances such as animal and vegetable oils before measuring 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.

3、 Instrument featuresPortable infrared spectrophotometer for oil analysis of animal and vegetable oils, petroleum products, and water-based oils

1. The exclusive safety protection box and its baffle can be used as an operation test bench, which is easy to carry, flexible to operate, and convenient for field testing.

2. The integrated optical system design has good stability and high seismic performance, and can work in a moving state.

3. Adopting a digital LCD screen with clear display and easy operation

4. Equipped with specialized analysis software, it has functions such as automatic statistical analysis, spectrum display, and storage

5. 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.

6. Can detect total oil, petroleum, animal and vegetable oils, and can also detect oil content in solid cooking fumes and gases in the catering industry;

7. The built-in lithium battery power supply can continuously measure over 1000 samples and run continuously for 8 hours upon startup;

8. Built in spectrum processing program, without the need for an external computer, can directly display the final results;
