Revolutionary Portable Exoscan Ftir Spectrometer

A2 Technologies has announced that its hand-held FTIR system Exoscan™, has the performance capability to provide accurate measurement of anodisation thickness and type on large parts, without the need to dissemble or otherwise modify the part for testing. 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 disassembling or destruction. Results demonstrate that by using the high performance external reflectance sampling interface, Exoscan can identify and quantify even the thinnest anodized 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 where the metal part is located, for example on the manufacturing floor or in a maintenance shop.
