GD-OIL8 Portable Infrared Oil Content Analyzer Measure Oil-Grease Content
I. Principle
When a monochromatic light through the test solution, the light will be absorbed, Light be absorbed proportional to the concentration of the test solution.
Conform Beer's law:
A= log (1/T)=log(I0 / I)
T ---------- Transmission
I0 ---------- Incident light intensity
I ---------- Transmitted light intensity
A --------- Absorbance
Oil concentration:
C=X×A2930+Y×A2960+Z×(A3030-A2930/F)
C is Oil concentration
A2930 A2960 A3030
-------Absorbance under different wavelengths
X,Y,Z,F is Correction factor
II. Features
1. This analyzer's operation principle and indexes totally comply to the national standard of "Water Quality-Determination of Petroleum, Animal and Vegetable Oils-Infrared Spectrophotometry"(GB/T 16488-1996).
2. Dismountable integrated optical system; small size; light weight; firstly spectral and then absorption in line with the requirements of the features of infrared spectroscopy; good stability; high SNR.
3. The electrical modulation source reduces the intensity of the heat source to facilitate system cooling; at the same time the non-mechanical light-cutting active devices simplifies the analyzer's structure thus improves its reliability.
4. The processing of the sensor signal uses lock-in amplifier circuit thus improves the analyzer's SNR and the minimum detection limit.
5. It can check whether the purity of extraction agent meets the measurement requirements or not.
6. Function of spectrum scanning and displaying the absorbance curve within the used spectrum range to distinguish the disruptor.
7. It can be used as an infrared spectrophotometer.
8. The carbon tetrachloride can be replaced by tetrachlorethylene extraction agent.
9. Special structure design of the cuvette available for any cuvette from 1cm to 5cm.
10. It has simple structure, self-contained optical system and electrical system, and integration of high degree thus its reliability and maintainability is improved a lot.
11. Easy operation. It only needs you to click your mouse once then the measurement of sample can be finished.
12. High speed of measurement. It just takes 30 seconds to finish a test.
13. Powerful functions of the software. Testing data and spectrograms can be saved to the hard disk for checking and printing anytime. It also has the functions of auto reset and regression equation calculation and so on.
