Extended Capabilities for Exoscan Handheld FTIR System from A2 Technologies
2 Feb 2011A new Spherical ATR Sampling interface enables the Exoscan to quickly and accurately analyze 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.
A new Spherical ATR Sampling interface enables the Exoscan to quickly and accurately analyze 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 makes ATR measurements using the Exoscan easy and minimizes the need for pressure devices to achieve high quality reproducible spectra. Two versions of the Spherical ATR are available. Exoscan's diamond ATR is an ideal universal interface for a broad range of solid materials, while the germanium ATR is well suited to the analysis of carbon black filled rubber or samples for which measurement of thin layers on the surface is critical.
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 analyzer for industries that must analyze measure a wide assortment of materials either in the lab, in the field or at the production line.
Graham Miller, president of A2 Technology comments: "FTIR's role in QA/QC has been traditionally a lab based effort where sample sets are brought to the instrument. With the development of the Exoscan, FTIR can take a role in quality assurance and quality control of products that are too large to be brought to the lab or otherwise cannot be effectively sampled. The development the spherical ATR enables Exoscan to quickly and reliably provide high quality measurements on a broad array of materials and surfaces."

A2 Technologies, LLCPerformance of the A2 Technologies Exoscan:• Exoscan provides the stability, sensitivity and overall performance to accomplish even difficult applications. A2 Technologies years of experience in designing portable FTIR spectrometers enabled the development of the miniaturized, yet rugged and high throughput Exoscan interferometer and optical system. • Exoscan is a true mid-infrared spectrometer with a frequency range of 4000-650 cm-1 and a maximum resolution of 4 cm-1, enabling Exoscan to excel at virtually any applications that use solid, semi-solid or liquid samples. By minimizing the beam path while keeping a large beam aperture, Exoscan is very compact, yet has superior signal-to-noise. • In addition, the sampling interfaces that are custom designed for the Exoscan are also designed to ensure the highest performance in the smallest package. Many of the applications below, which were originally developed on traditional lab FTIR spectrometers, are readily transferred to the Exoscan system. Exoscan’s superior performance capabilities enable both methods developers and end-use operators to successfully use the system for their individual requirements.
