FTIR Fourier Transform Infrared Spectrophotometry is a sensitive technique particularly for identifying organic chemicals in a whole range of situations including solid, liquid and gas samples. FTIR can also be used to characterise some inorganic compounds. It may be used to identify both pure compounds and simple mixtures.
LPD Lab Services instruments also feature an ATR imaging system that enables the collection of high resolution infrared images of extremely small samples to examine the composition of individual particles and materials based on FTIR spectral data. Examples include paints, adhesives, resins, polymers, rubbers, coatings, pharmaceuticals and additives used in food and other consumer goods. It is a particularly useful tool in isolating and characterising organic contamination.
Typical Applications of FTIR and FTIR Microscopy
