Abstract:

This study discusses the design, development, and construction of a low cost optical multisensor system. The light sources in the proposed system are lanthanide(III) complexes emitting light in the near infrared spectral region. Through the ability to adjust the source wavelength these measuring platform can be used for a variety of practical tasks. The feasibility of the developed devices has been demonstrated for analysis of milk samples.

Keywords: NIR spectroscopy; optical multisensor system; lanthanide(III) complexes; milk analysis; urea; chemometrics
