Fourier transform infrared spectrometer is abbreviated as FTIR. It is mainly composed of the infrared light source, interferometer, sample chamber, detector amplifier, an analog-to-digital converter (A/D), and computer composition.
Principle: Fourier transform infrared spectroscopy(FTIR) is widely used for characterizing bulk solids, powders, liquids or gases. Different functional groups, chemical bonds vibrate or rotate, and absorb infrared light with different wave numbers. According to the peak position, it can be determined which functional groups or chemical bonds exist in the sample, which can be used for qualitative and quantitative research on substances.
Usages: It can carry out qualitative and quantitative analysis of samples and is widely used in the fields of medicine and chemical industry, geology and mining, petroleum, coal, environmental protection, customs, gem identification, criminal investigation identification, etc.
Features of FTIR Spectrophotometer
- High sensitivity and stability
- Intelligent real-time monitoring of instrument status
- Multiple communication
- Flexible and convenient testing
- Powerful software workstation
- High sensitivity optical system: cube-corner Michelson interferometer combined with patented fixing mirror alignment technology
- High stability modular partition design, greatly improves the mechanical stability and long-term working stability of the instrument.
- Innovated integration electronic system, high sensitivity pyroelectric detector pre-amplifier technology, dynamic gain amplification technology, high precision 24-bit A/D conversion technology, real-time control and data processing technology, digital filter, and network communication technology, ensuring high quality real-time data collection and high-speed transmission.
- High intensity IR source assembly: High intensity, long lifetime IR source module, with the highest energy distributed in the fingerprint region, adopts a reflex sphere design to obtain even and stable IR radiation. External isolated IR source modules and large space heat dissipation chamber designs provide higher thermal stability and stable optical interference.
What are the Advantages of FTIR?
- It has high characteristic for the detection of different functional groups or chemical bonds.
- It uses less sample, has fast analysis speed, and does not damage the analyzed sample.
- It can conduct qualitative and quantitative analysis of material components, and analyze a wide range of materials.
- It has exquisite appearance, is lightweight, and is shockproof.
- It uses Ethernet and WIFI dual-mode communication, which is convenient for users to conduct interconnected testing and remote operation.
- It adopts a large sample chamber design, which can be matched with a variety of infrared spectroscopy accessories for a wider range of sample analysis.
FTIR Common Test Methods
- Transmission Experimental Mode (FTIR)
In the FTIR transmission sampling technique experimental mode, incident infrared light passes through the sample and is measured by the FTIR detector to generate a spectrum.
- Attenuated Total Reflection Experimental Mode (ATR-FTIR)
In the ATR-FTIR attenuated total reflection sampling technique experimental mode, infrared (IR) light passes through a crystal and is totally reflected at least once at the crystal-sample interface; the reflected light is transmitted to the FTIR detector.
- Specular Reflection Experimental Mode
Commonly used for FTIR detection of liquids, films and bulk materials.
- Diffuse Reflection Experimental Mode
Commonly used for FTIR detection of powder samples.
- Powerful Database of FTIR:
- 20 professional spectral libraries with more than 15,000 spectra;
- Catalyst Library, Chemical Reagent Library, Oil And Additives Library, Polymer Library, Organic Reagent Library, Veterinary Drugs Library, etc.

Applications of FTIR Spectrophotometer
- Identification of known objects.
- Structure identification of unknowns.
- Quantitative analysis of special materials.
- Micro-infrared can analyze trace substances such as residues on the surface of the product, powder/liquid precipitated on the surface, suspected oxidation, corrosion, foreign matter, and introduction of foreign components on the surface of the product.
Among them, FTIR has an excellent performance in determining the consistency of polymer materials.
The purpose of material consistency determination:
- Solve the abnormal problem of the product from the aspect of the material.
- Monitor the product to determine whether the material has the same ingredients, the same batch, and the same manufacturer.
- It can effectively control the excessive use of recycled materials or scraps by plastic material suppliers.
- Reverse analysis of products, accurate qualitative unknown materials, and cost savings.
Application areas: It is widely used in the fields of medicine, chemical industry, geology and mining, petroleum, coal, environmental protection, customs, gem identification, criminal investigation, and identification. We provide nearly 20 detection spectra for customers to use.
