Analytical study of canvas painting collection from the Basilica de la Virgen de los Desamparados using SEM/EDX, FT-IR, GC and electrochemical techniques

摘要

A new method, based on the combined use of scanning electron microscopy-x-ray microanalysis, Fourier tranform infrared spectroscopy, gas chromatography and differential pulse voltammetry, is proposed which permits a parallel investigation of organic and inorgaic materials and the characterization of the artisitic technique employed in canvas painting. The proposed method has led to analyze succesfully the canvas painting collection exhibited in the Basilica de la Virgen de los Desamparados (Valencia, Spain) which includes art works from 17th to 20th century.
