Fourier Transform Infrared and Raman Spectrometer

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.

There are many types of samples can be analyzed including 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. It 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.

Applications of FTIR Spectrophotometer

FTIR Qualitative Analysis
Qualitative Analysis
FTIR Quantitative Analysis
Quantitative Analysis
  1. Identification of known objects.
  2. Structure identification of unknowns.
  3. Quantitative analysis of special materials.
  4. 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:

  1. Solve the abnormal problem of the product from the aspect of the material.
  2. Monitor the product to determine whether the material has the same ingredients, the same batch, and the same manufacturer.
  3. It can effectively control the excessive use of recycled materials or scraps by plastic material suppliers.
  4. 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.

FTIR Common Test Methods

  1. 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.

Transmission Experimental Mode ftir
  1. 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.
