An Eye-One Pro mini-spectrophotometer as an alternative to diffuse reflectance spectrometer

The potential of an Eye-One Pro mini-spectrophotometer and a monitor calibrator as a recording instrument for measuring diffuse reflectance spectra and chromaticity coordinates in the Lab system was studied by an example of polyurethane foam-based color scales. Some analytical characteristics of this instrument were compared with the characteristics of a Spektroton laboratory colorimeter. It was shown that an Eye-One Pro mini-spectrophotometer could be used for determining compounds after the formation of a colored product in the solid phase. A relatively low cost, compatibility with computer systems, rapid processing of large data sets, and the possibility of work with small adsorbent portions are among the advantages of the Eye-One Pro.
