Infrared Spectroscopy (FTIR)
Project Introduction
Infrared spectrum analysis is an analysis and identification method that combines the mathematical processing of Fourier transform and computer technology with infrared spectrum. It is mainly composed of optical detection part and computer part. Infrared spectroscopy can be used to study the structure and chemical bonds of molecules and as a method to characterize and identify chemical species. The infrared spectrum is highly characteristic and can be analyzed and identified by comparing it with the infrared spectrum of a standard compound.

use
Infrared spectroscopy can be used to study the structure and chemical bonds of molecules and as a method to characterize and identify chemical species. The infrared spectrum is highly characteristic and can be analyzed and identified by comparing it with the infrared spectrum of a standard compound. Several standard infrared spectrum sets have been published in volumes. These spectra can be stored in a computer for comparison and retrieval, and for analysis and identification. The characteristic wavenumber of chemical bonds is used to identify the type of compound and can be used for quantitative determination. Due to the interaction of adjacent groups in the molecule, the characteristic wave number of the same group in different molecules has a certain range of variation. In addition, infrared spectroscopy is also widely used in the study of the configuration, conformation, and mechanical properties of polymers, as well as in the fields of physics, astronomy, meteorology, remote sensing, biology, and medicine.
Foreign body analysis
Purpose: Help customers analyze unknown substances appearing on the surface, surface residues, precipitates, particulate matter components, etc.
Scope of application: component analysis of unknown organic components in products.

Test application:

Consistency analysis
Purpose: To verify whether the materials of two or more samples are consistent, to verify whether the samples are consistent with the drawing specifications, to help customers avoid repeated problems such as material degradation, recycled materials, material inconsistencies, etc., and to achieve the purpose of monitoring products.
Scope of application: Determination and comparison of organic matter in products
Test application:

Consistency analysis of infrared spectrum analysis

The main FTIR peaks of the two black plastics are similar. If you identify carefully, one sample is PC and the other sample is PC/ABS, so the materials of the two samples are inconsistent.

Principal component qualitative/quantitative analysis
Purpose: Qualitative and quantitative analysis of the main components in the sample. The main components are often polymers, fillers, flame retardants, etc. Help customers verify whether supplier materials meet specifications, analyze competitor sample materials, etc.
Scope of application: Suitable for principal component analysis of unknown materials.
