Principal component analysis is used to examine large multivariate databases. The graphical approach to exploratory data analysis is described and illustrated with a single example of chemical composition data obtained on environmental dust particles. While the graphical approach to exploratory data analysis has certain advantages over the numerical procedures, the empirical approach described here should be viewed as complementary to the more robust treatments that statistical methodologies… 
Chemometrics for environmental monitoring: a review.
This review aims to provide a detailed understanding of chemometric techniques, how they are currently used in environmental monitoring, and how these techniques can be used to improve current practices.
The use of principal component analysis for the modelling of high performance liquid chromatography
Abstract Principal component analysis (PCA) was used to analyse the behaviour of a chromatographic separation as its scale increased. Three 4.6 mm diameter columns identical in every respect except
Library Search — Principles and Applications
The principles of this methods, the design and the structure of spectra libraries and the manifold of different search strategies are explained and some important applications demonstrated.
Detecting subtle hydrochemical anomalies with multivariate statistics: an example from ‘homogeneous’ groundwaters in the Great Artesian Basin, Australia
The major ion composition of Great Artesian Basin groundwater in the lower Namoi River valley is relatively homogeneous in chemical composition. Traditional graphical techniques have been combined
Multivariate statistical analysis of gas chromatograms to differentiate cocoa masses by geographical origin and roasting conditions
Multivariate statistical methods were applied to the differentiation of cocoa from 13 geographical origins, taken at four roasting steps and supplied by five different manufacturers. An analysis of
Effect of white noise on abstract factor analysis using simulated equilibrium data
Principal component (PC) eigenvalues and varimax rotated factor loadings from abstract factor analysis were studied to determine the effect of white noise from measurement and sampling processes on
