“…Two pharmaceutical excipients (lactose monohydrate and microcrystalline cellulose) and one API (acetaminophen) were used, and investigated using NIRS and partial least squares (PLS) by Sánchez-Paternina et al 10 For pharmaceutical industry examples using NIRS technique, we can cite special interest in the identification of raw materials and finished products, 11 reaction monitoring in blending processes, 12 determination of active principles, 13 dissolution testing, 14 hardness testing 15 and polymorphs. 16 The use of appropriate mathematical and statistical methods (i.e., chemometrics) is largely responsible for the advancement of the NIR technique, including multivariate calibration techniques such as partial least squares (PLS), 17 principal component regression (PCR), 18 artificial neural networks (ANN) 19 and least squares-support vector machine (LS-SVM). 20 The main advantages of using the multivariate calibration techniques listed above is that fast, cheap, or non-destructive analytical measurements (such as NIRS) can be used to estimate sample properties (for example, physicochemical parameters of pharmaceutical formulations) which would otherwise require time-consuming, expensive or destructive testing (such as liquid chromatography).…”

“…In fact, NIRS is a simple, expeditious, non-destructive instrumental technique and NIR spectra provide both physical and chemical information about solid samples. As a result, its use combine with chemometrics data processing have turned it into a promising tool for process control within the framework of PAT [3][4][5][6][7][8][9][10].…”

“…In previous works, accuracy profiles, a statistical approach based on ␤-expectation tolerance intervals was found to be advantageous to evaluate quantitative method accuracy in pre-validation and validation stages [18][19][20].…”
