Infrared absorption spectroscopy is a versatile and cost effective measurement technique that combines molecular specificity with easy quantitation. The technology for making routine measurements in the laboratory is now mature and standard commercial Fourier transform instruments give very high levels of performance at reasonable cost. This has meant that FT-IR systems have become ubiquitous in analytical laboratories where they are used for the identification and characterization of molecular samples that range from pharmaceuticals and fine chemicals through to polymers, and foodstuffs. These are discussed here along with newer approaches that have potential to extend the range of applications of IR absorption measurements to other industrial purposes including imaging for characterization of micro- or nanostructured materials, process monitoring (particularly of biological processes) and miniaturized IR spectrometers.
