A2 Technologies has expanded the sampling capability of its Exoscan handheld FTIR system. A new spherical ATR sampling interface enables the Exoscan to quickly analyse a wide range of materials typically encountered in the QA/QC lab, or at the production line. These materials include powders and granules as well as large samples such as polymer, composite and plastic sheets.
The new design facilitates taking ATR measurements using the Exoscan while minimising the need for pressure devices to achieve high quality reproducible spectra. Two versions of the spherical ATR are available: The company's diamond ATR, suitable for a range of solid materials, and the germanium ATR, suited to analysis of carbon black-filled rubber or samples for which measurement of thin surface layers is required.
The Exoscan adds the spherical ATR capability to its other sampling technologies, which include diffuse reflectance for absorbing or scattering samples, specular reflectance for coatings on reflectance surfaces and grazing angle reflectance for the measurement of very thin layers on metal surfaces. These sampling interfaces can be interchanged in seconds, making Exoscan an ideal QA/QC analyser for industries that must measure a wide assortment of materials either in the lab, in the field or at the production line.
