Accurate analysis of metal coating by
spectrometer
The A2 Technologies hand-held FTIR spectrometer system Exoscan can provide accurate measurement of anodisation type and thickness on large parts, without the need to dis-assemble
In a new application note entitled "Metal Coatings Analysis Using the Exoscan Hand Held FTIR", the system demonstrates why it is ideal for non-destructive analysis of samples that are too large to bring to the laboratory or too valuable to require a small portion to be removed for analysis Weighing less than seven pounds, the portable, hand-held A2 Technologies Exoscan allows even large complex parts to be directly measured in any orientation eliminating the need for sample disassembly or destruction

A2 Technologies, the innovator and manufacturer of portable Fourier Transform Infrared (FTIR) spectrometers, launches Exoscan, the smallest, most compact FTIR spectrometer available on the market
Results demonstrate that by using the high performance external reflectance sampling interface, Exoscan can identify and quantify even the thinnest anodised coatings as well as paint and primer coatings on metal surfaces.
Since a variety of coatings can be used to protect a metal surface from corrosion or to impart specific properties, it is important to ensure that the selected coating has been applied via the correct process and at the desired thickness.
Infrared spectroscopy has been shown to be capable of carrying out this coating verification, but only using laboratory spectrometers and only for samples that were the proper shape and size to be accommodated by the spectrometer.
Exoscan enables the coatings on any size surface to be analysed directly, in situ, where the metal part is located, for example on the manufacturing floor or in a maintenance shop.
