Construction of different calibration models by FTIR/ATR spectra and their application in screening of phenylketonuria

This paper is aiming at constructing different calibration models by using FTIR/ATR spectra and applying them for the screening of phenylketonuria for the newborns. We proposed a cKPLS model, which is integrated with the kernel function and the consensus strategy. After a careful comparison, the cKPLS model performed the best, and the result yielded were much more accurate and stable.103
