MT-O1200 Portable Infrared Oil in Water Analyzer

MT-O1200 Portable Infrared Oil in Water Analyzer

Application：

This portable infrared oil in water analyzer is used for the determination and detection of petroleum and animal and vegetable oil content in groundwater, surface water, domestic sewage and industrial wastewater, as well as the concentration of cooking fume in the catering industry.

The oil substances in the water are extracted with tetrachloroethylene or CCl4, and the total extract is determined. Then the extract is adsorbed with magnesium silicate. After removing polar substances such as animal and vegetable oils, the petroleum is determined. The content of total extract and petroleum are calculated by the absorbance A2930, A2960 and A3030 at the 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). The content of animal and vegetable oil is calculated as the difference between the total extract and the content of petroleum. The state promulgated the "Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared Spectrophotometry" (HJ 637-2018) standard, and all performance indicators are at an advanced level.

Features：

1. A true infrared spectroscopic three-wave number oil tester, which comprehensively examines the stretching vibration of the C-H bond in the CH2 group in the oil (determined by 2930cm-1), the stretching vibration of the C-H bond in the CH3 group (determined by 2960cm-1) and the stretching vibration of the C-H bond in the aromatic ring (determined by 3030cm-1), and the measurement results are not affected by changes in the oil components.

2. No need to make a standard curve, no need to adjust the zero point, full scale, no need to calibrate, and the sample can be measured directly.

3. A cuvette can be used to eliminate the influence of the difference between cuvettes on the measurement results, and the measurement accuracy is higher. When using multiple cuvettes, a cuvette database is provided, which has the function of saving cuvette data and automatically deducting the cuvette background.

4. Long-life light source, no need to replace the light source.

5. Modulated light source, high signal frequency, frequency selection amplification, signal output is not affected by stray light.

6. The grating is controlled by a precision stepper motor, with automatic wavelength correction function, high wavelength accuracy and good repeatability.

7. The semiconductor detector has a long service life. The semiconductor cooling technology is applied to make the signal output more stable and the signal output is not affected by room temperature changes.

8. Powerful functions: It has multiple functions such as infrared spectrophotometry, non-dispersive infrared photometry, spectrum scanning, etc., with a wide scanning range, and can be used as an infrared spectrometer.

9. It has an automatic light source compensation system and a signal drift correction system, and the baseline has no drift.

10. Built-in single-chip microcomputer control, LCD display, can work independently without a computer. It can also be connected to the computer control host through the USB interface, with complete functions and easy operation.

11. On the same desktop, the spectrum, measurement steps, and measurement results are displayed at the same time. The wave number position, absorbance and transmittance of any point in the spectrum can be read in the spectrum.

12. The spectrum, measurement conditions, and measurement results can be saved in a computer file or directly printed out.

13. Fast detection speed: 25 seconds/time for infrared spectrophotometry and 2 seconds/time for non-dispersive infrared photometry.
