Title: Comparison Of Multivariate Calibration With PCR And PLS For Glucose Using Infrared Spectra Of Human Whole Blood
Abstract: The calibration of glucose in whole EDTA blood was carried out using FT-IR spectra obtained with a micro-CIRCLE cell in the range of 1500 - 750 cm-1. The reference concentrations had been measured by the enzymatic glucose dehydrogenase method. The P-matrix approach was chosen applying the Partial-least-squares (PLS) and Principal component regression (PCR) algorithms. The optimum model for predictipns was obtained by PLS achieving an average prediction error of 19.8 mg/dL based on PRESS1 from crossvalidation. The calibration results for both algorithms are discussed. PLS is favoured on the grounds of numerical and statistical advantages.
