1. Project introduction:

Fourier Transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas, measuring how much light a sample absorbs at each wavelength. It is widely used in the qualitative and quantitative analysis of many polymer and inorganic non-metallic materials such as plastics, rubber elastomers, fibers, coatings, fillers, etc. Identification of organic compounds, understanding of analytical structures, process control of organic substance use, polymer/materials research.

It can be used for the identification of known substances, the structural identification of unknown substances, the quantitative analysis of special materials, and microscopic infrared can analyze trace substances such as product surface residues, surface precipitation powder/liquid, suspected oxidation, corrosion, foreign matter, and foreign component introduction on the surface of the product.

2. Application advantages

Infrared spectroscopy has strong characteristics, fast analysis, no damage to the sample, small sample dosage, easy operation, can analyze samples in various states, high analytical sensitivity, wide application range (solid, liquid or gaseous samples can be applied; Inorganic, organic, polymer compounds can be detected) and other characteristics, which are combined with chromatography (GC-IR) or TGA (TGA-IR), and have powerful qualitative functions.
