Near-infrared spectroscopy and multivariate calibration for the quantitative determination of certain properties in the petrochemical industry

Quantification of total polysaccharides and triterpenoids in Ganoderma lucidum and Ganoderma atrum by near infrared spectroscopy and chemometrics

“…In such case, useful multivariate calibration tools, such as partial least-squares (PLS), principal component regression (PCR), multiple linear regressions (MLR) and artificial neural networks (ANNs), are available. With the aid of chemometrics, this technique has already been used to determine the internal quality of products in diverse fields, for example in food industry (Lachenmeier, 2007;Small, 2006), agriculture (Buning-Pfaue, 2003), pharmaceutical industry (Dempster, MacDonald, Gemperline, & Boyer, 1995;Li, Chen, Xiang, & An, 2000;Luypaert, Heuerding, de Jong, & Massart, 2002;Smola & Urleb, 2000), and petrochemical industry (Macho & Larrechi, 2002;Macho, Sales, Callao, Larrechi, & Rius, 2001;Blanco et al, 2001), etc.…”

Rapid analysis of polysaccharides contents in Glycyrrhiza by near infrared spectroscopy and chemometrics

“…As a rapid, economical and nondestructive analytical technique, NIR spectroscopy has gained wide acceptance in food industry, agriculture, pharmaceutical industry, and petrochemical industry [10][11][12][13][14]. The principle of NIR measurement is based on the correlation between the NIR absorption at different wavelength and the data of sample composition obtained by reference method.…”

Analysis of polyolefin compositions through near infrared spectroscopy

“…[1][2][3] NIR-based techniques present substantial advantages when compared to other conventional analytical techniques. For this reason, the field has been reviewed by different authors.…”
