Encoded Photometric IR Spectroscopy Offers an FTIR Alternative
If Aspectrics, Inc., has its way, its new Encoded Photometric Infrared Spectroscopy (EP-IR) analyzers will soon begin to replace NDIR, FTIR and gas chromatographic technologies in process instrumentation. Aspectrics recently began shipping evaluation units of its EP-IR technology to companies that manufacture analytical and process instrumentation. Specific details of individual technology evaluation agreements were not disclosed.“We believe that an opportunity exists for EP-IR to replace the Nondispersive Infrared (NDIR), Fourier Transform Infrared (FTIR) and gas chromatographic technologies currently used for process monitoring and environmental applications," said Paul H. Salsgiver Jr., CEO of Aspectrics, Inc. "A single EP-IR system can replace multiple NDIR modules and provide better performance.”At the heart of Aspectrics’ EP-IR analyzer is a rotating disc onto which up to 256 concentric encoding tracks is formed. The EP-IR analyzer continuously acquires data on every optical channel in parallel to provide the most accurate intensity measurements. The encoding tracks of the EP-IR analyzer replace the detector elements of a conventional detector array, effectively providing NDIR ruggedness with FTIR performance, according to Aspectrics.
