X-ray scattering spectroscopy associated with chemometrics (eerx)

摘要

"X-ray scattering spectrometry (eerx) combined with chemometrics.The present invention relates to development, optimization and evaluation of an analytical method for organic and inorganic substances, using scattered sources of X-rays.With the resolution achieved by the use of chemometric tools. In this new method, the samples of organic or inorganic nature are subjected to radiation.The spectra obtained are arranged in matrix form and the data when are treated by using multivariate chemometrics. If not, is used univariado treatment.In this manner, information can be obtained from both qualitative and quantitative.This new method called X-ray scattering spectrometry (eerx) was developed, optimized and evaluated in two analytical applications.The first related to the classification of samples as standards useful in environmental analysis and animal metabolism, and the other,Related to quantitative measurement of molar mass of natural organic polymers.
