Infrared Spectrometer

An infrared spectrometer is an instrument that analyzes molecular structure and chemical composition by utilizing the absorption characteristics of substances to infrared radiation at different wavelengths. It typically consists of a light source, monochromator, detector, and computer processing information system. It is widely used in research fields such as dyeing and textile industries, environmental science, biology, materials science, polymer chemistry, petroleum industry, and biomedical science.

Analytical Principle:

Infrared spectroscopy is essentially an analytical method that determines molecular structures and identifies compounds based on information such as relative vibrations between atoms within molecules and molecular rotations. Depending on the spectroscopic device, infrared spectroscopy can be divided into dispersive and interferometric types. For dispersive infrared spectrometers, when a sample absorbs infrared radiation of a certain frequency, the vibrational energy levels of the molecules transition, reducing the intensity of the corresponding frequency in the transmitted beam. This creates an intensity difference between the reference and sample light paths, resulting in the infrared spectrum of the measured sample.

Application Fields:

1. Identification and structural analysis of unknown compounds;

2. Quantitative analysis of compounds, chemical reaction kinetics, crystal transformation, phase transition, and studies on the transient relationships of material stretching and structure;

3. Continuous monitoring of industrial processes and atmospheric pollution;

4. Monitoring of free silicon dioxide in the coal industry;

5. Testing in the jewelry industry;

6. Measurement of hydroxyl groups in crystal quartz;

7. Composition analysis of polymers;

8. Numerous fields including health quarantine, pharmaceuticals, food, environmental protection, petroleum, chemical industry, optical coatings, optical communication, and materials science.
