Why ftir is used

FTIR - Fourier Transform Infrared - spectroscopy analysis and testing identifies chemical compounds in a wide range of capacities. FTIR analysis helps clients understand materials and products. Analytical testing sample screens, profiles and data interpretation are available on a global basis from our experts who deploy FTIR to identify chemical compounds in consumer products, paints, polymers, coatings, pharmaceuticals, foods and other products. FTIR offers quantitative and qualitative analysis for organic and inorganic samples.

The spectra produce a profile of the sample, a distinctive molecular fingerprint that can be used to screen and scan samples for many different components. FTIR is an effective analytical instrument for detecting functional groups and characterizing covalent bonding information.

FTIR combined with these techniques provides complementary data regarding a molecule's molecular structure. Intertek Global Website. Toggle navigation Intertek. Industries Services. The signal can be measured quickly. Then, the signal is decoded by applying a mathematical technique known as Fourier transformation. This computer-generated process then produces a mapping of the spectral information.

The resulting graph is the spectrum which is then searched against reference libraries for identification. With the microscope attachment, samples as small as 20 microns can be analyzed. This allows quick and cost effective identification of unknown particles, residues, films or fibers. FTIR testing can also measure levels of oxidation in some polymers or degrees of cure in other polymers as well as quantifying contaminants or additives in materials. Scecina, J.
