Standardisation of near-infrared spectrometric instruments using the piecewise direct standardisation method is studied. Two important steps of this method, namely the selection of the subset samples and the determination of the local optimal number

The transfer of calibration models between near-infrared spectrometric instruments with the algorithm proposed by Shenk and Westerhaus as a standardization method is studied. This algorithm does not yield optimal results when standardization samples

In this paper, transfer of calibration models between near-infrared spectrometric instruments using three different standardisation sets is described. The first set contains samples which are very similar to the agricultural samples from three differ

After a multivariate calibration model is built and validated, it is ready to be used for the prediction of the characteristic to be determined in the new samples. Before prediction, one should make sure that the new samples are similar to the calibr

A procedure to check the validity of near-infrared calibration models over time is proposed. Validation samples are analyzed at regular time intervals by both near-infrared and reference methods in order to check the validity of the near-infrared cal

A new standardization method based on transferring near-infrared (NIR) spectra in the wavelet domain is proposed. For each NIR spectrum, wavelet transform coefficients are computed, and the transfer step is performed by relating the wavelet transform

A new approach is proposed for the detection of changes in the instrumental response of near-infrared spectrometers over time. This approach is based on simulating possible instrumental differences and performing a principal component analysis of the
