BACKGROUND AND METHODS Several standard powdered black pigments were characterized by means of thermogravimetry TG-DTG and allied techniques. These pigments were used to make standard plaster frescoes at this purpose prepared. The latter ones were subjected to Raman and reflectance analysis. The results obtained, together with TG data, were chemometrically processed and used to identify an anal...

A NIR-chemometric method, that is able to directly quantify the active pharmaceutical ingredient (API) and two major excipients in pharmaceutical powder blends for manufacturing indapamide sustained release (SR) tablets, was developed and fully validated. In order to develop calibration models for the assay of indapamide, hydroxypropylmehylcelulose (HPMC) and lactose, the NIR spectra of 25 seri...

This supplement contains an accurate selection of papers based on the research presented at the 3 edition of the International Meeting CMA4CH with a balance in the three main topics. The meeting was held in Taormina on 26-29 September 2010 and the main aim was to favour the meeting of all professional figures involved in the protection of cultural heritage (CH) as well as of the environment. In...

In this study, chemometric method is employed to identify anthropogenic effects on the water quality in Sanya Bay, South China Sea, and its marine and natural characteristics. Principal component analysis has extracted the four latent factors, thus explaining 85.52% of the total variance. Cluster analysis and principal component analysis have identified three different patterns of water quality...
