Journal Highlight: Assessment of resin formulations and determination of the formaldehyde to urea molar ratio by near- and mid-infrared spectroscopy and multivariate data analysis
spectroscopyNOW
Apr 15, 2013
The molar ratios of formaldehyde to urea in resin formulations have been analyzed by ATR-FTIR and FT-NIR spectroscopy, using PCA to separate them according to molar ratios and to distinguish between two groups of resins, and SIMCA to classify new resin samples.

The emphasis of this book is on understanding the principles and applications behind the main ideas in chemometrics, which can then be applied to a wide variety of problems in chemistry, chemical engineering and allied disciplines.
Data analysis is a vital part of science today, and in assessing quality, multivariate analysis is often necessary in order to avoid loss of essential information.
Factor analysis is a mathematical tool for examining a wide range of data sets, with applications especially important to the design of experiments (DOE), spectroscopy, chromatography, and chemometrics. In this free chapter from "Factor Analysis in Chemistry" Edmund Malinowski introduces the technique, declaring that "every problem has a solution"!
