Comparative studies between miniaturised and conventional spectrometers are required to evaluate whether new instrumental developments can effectively substitute laboratory instruments. This article reports on a comparative performance test based on the quantitative results obtained with the spectral data of a solid pharmaceutical formulation measured in diffuse reflection with a benchtop NIR instrument and a hand-held NIR spectrometer.
