A Portable Infrared Attenuated Total Reflection Spectrometer for Food Analysis
Description
The analytical performance of a compact infrared attenuated total reflection spectrometer using a pyroelectric detector array
has been evaluated and compared to a conventional laboratory Fourier transform infrared system for applications in food
analysis. Analytical characteristics including sensitivity, repeatability, linearity of the calibration functions, signal-to-noise
ratio, and spectral resolution have been derived for both approaches. Representative analytes of relevance in food industries
(i.e., organic solvents, fatty acids, and mycotoxins) have been used for the assessment of the performance of the device and to
discuss the potential of this technology in food and feed analysis.
