OIL -8 type infrared spectrophotometer | economical infrared oil analyzer

1、 Instrument Introduction:

OIL-8The Type X infrared oil analyzer adopts the principle of infrared spectrophotometry and follows the“HJ 637-2012Water quality - Determination of petroleum, animal and vegetable oils The new generation of infrared oil analyzer is designed in accordance with the requirements of infrared spectrophotometry. After connecting to a computer, the instrument can display the positions of spectra and absorption peaks, and can quickly and accurately measure the oil content in water. It is widely used in industries such as petroleum, chemical, scientific research, and environmental monitoring.

Total oil: refers to theHJ637-2012Under the specified conditions, it can be extracted by CCl4 and has a wavenumber of2930 cm-1、2960 cm-1、3030cm-1Substances with characteristic absorption at all or part of the spectral bands, mainly including petroleum and animal and plant oils.

Petroleum category:Refers to inHJ637-2012A substance that can be extracted by CCl4 under specified conditions and is not adsorbed by magnesium silicate.

Animal and vegetable oils:Refers to inHJ637-2012A substance that can be extracted by CCl4 and adsorbed by magnesium silicate under specified conditions.

2、 Instrument principle

Extract oil substances from the sample using CCl4, determine the total oil content, and then adsorb the extract with magnesium silicate to remove polar substances such as animal and vegetable oils, and determine the petroleum content. The total oil and petroleum content are determined by wave numbers, respectively2930cm-1（CH2Within the functional groupC—HThe stretching vibration of keys2960cm-1（CH3Within the functional groupC—HThe stretching vibration of keys) and3030cm-1(In the aromatic ring)C—HThe absorbance at the spectral band of the stretching vibration of the keyA2930、A2960、A3030Calculate the difference as the concentration of animal and plant oils.

4、 Instrument features

1The instrument is equipped with an RS232 data interface, which can be connected to a computer RS232/USB interface for uploading experimental data or printing;

2The detachable integrated optical system makes the instrument small in size, short in optical path length, and high in energy. It separates the light first and then absorbs it, which meets the requirements of infrared spectroscopy. It has good stability and high signal-to-noise ratio.

3By using electrically modulated light sources, the heating intensity of the light source is reduced to facilitate system heat dissipation. At the same time, due to the absence of mechanical cutting motion components, the instrument structure is simplified and the reliability of the instrument is improved.

4High stability, zero point24The change within an hour does not exceed ±1%

5Non 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.

6The analysis efficiency is high, and the instrument is60The analysis and determination of a sample can be completed within seconds.
