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.
Infrared Spectroscopy FTIR
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.
