Abstract

Micro-Infrared Spectroscopy (μSR-FTIR) and X-ray diffraction (μSR-XRD) with synchrotron light, Gas Chromatography/Mass Spectrometry (CG/MS), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM/EDS) were used to obtain the distribution of calcium salts of low molecular weight organic acids (LMWOA) in micro-layered micro-samples.
