Calibration Transfer between NIR Diode Array and FT-NIR Spectrophotometers

In this paper, the piecewise direct standardization method (PDS) has been used to transfer near-infrared calibration models for the soluble solids content of apple developed for o­ne spectrophotometer to another. The spectra were collected o­n three different devices: a Fourier transform (FT) spectrophotometer and two Diode Array (DA) spectrophotometers. The standardization procedure was performed o­n a first set with 520 Jonagored apples and a second with 1052 Jonagored and Golden apples. The performance of the standardization procedure was evaluated based o­n their RMSEP values. Far both ,is the RMSEP after carrying out the PDS procedure decreased, indicating an improvement in the prediction of SSC of apples, when spectra were collected o­n a DA spectrometer (slave) and the calibration constructed based o­n spectra of the same fruit but collected o­n a FT spectrometer (master).
