Abstract
Quantitative analysis of complex mixtures is a challenge for the analytical chemist. Most of the time it involves separation and purification steps which can be delicate, time consuming, and very costly. However, in the last few decades, the multivariate statistical analysis has emerged and there is now evidence in the literature that mathematical techniques can help extract useful information from real complex analytical systems, without any separation or purification steps. Reported here-in is an application of the multivariate methodology to Fourier transform infrared (FTIR) absorption spectroscopic data. The three steps process beings with the mathematical modeling of the relation existing between the concentrations of the constituents of a series of samples and their measured infrared spectra. This model is validated and then used to estimate the constituents concentrations of an unknown using its infrared spectrum. The systematic procedure that leads to an accurate and efficient model is described and includes the selection of the infrared method of analysis, the evaluation of the feasibility of the application, the experimental design conception, the selection of the appropriate mathematical algorithm and the validation of the model.
