Fourier Transform Infrared Spectroscopy

Fourier Transform Infrared Spectroscopy (FTIR) is a technique which is used to analyze the chemical composition of many organic chemicals, polymers, paints, coatings, adhesives, lubricants, semiconductor materials, coolants, gases, biological samples, inorganics and minerals. FTIR can be used to analyze a wide range of materials in bulk or thin films, liquids, solids, pastes, powders, fibers, and other forms. FTIR analysis can give not only qualitative (identification) analysis of materials, but with relevant standards, can be used for quantitative (amount) analysis.

FTIR can be used to analyze samples up to 11 millimeters in diameter, and either measure in bulk or the surface. Standard FTIR analysis covers the wavelength range of 2.5 to 25 um (4000 – 350 cm-1) and the instrument range can be expanded to cover 1 to 25 um (10,000 to 350 cm-1).
