CGA is a new facility of the University of Palermo born in 2006 and consists of advanced laboratories and instrumentations for possible applications on cultural heritage: i) Transmission Electron Microscopy (TEM) laboratory with Cryo-ultramicrotomy preparation laboratory. CGA 200 kV TEM permits the visualization of nanometre size particles inside electron transparent matrixes. Microdestructive characterizations of metallic nanoclusters inside ancient glasses and lustre or visualization of biological tissues in fossils are cutting edge possible cultural heritage applications; ii) Nuclear Magnetic Resonance (NMR) laboratory. CGA NMR 400 MHz spectrometer is equipped with three probes for solid, liquid and semisolid samples, allowing an almost infinite feasibility for the analysis of organic materials. Cultural heritage applications include fingerprinting recognition of different binding media, evaluation of conservation state of ancient paper artefacts, characterization of new chemicals for restoration and conservation; iii) High Performance Liquid Chromatography (HPLC) – Mass Spectrometry (MS) laboratory. This laboratory has two instruments: an HPLC coupled with a quadrupole – time of flight (Q-TOF) MS and another HPLC coupled with a triple quadrupole (Q-q-q) mass analyzer. They represent the state of the art instrumentations for the separation and characterization of macromolecular polar complex mixtures (e.g. proteinaceous binding media in paintings or wood varnishes); iv) Small Angle X-rays Scattering (SAXS) laboratory. The instrument permits to collect information about shape and dimensions of inhomogeneities, characteristic distances in partially ordered materials and pore profiles in mesoporous and nanoporous materials. It is advisable for studying surface of archaeological alloys, distribution of crystallites dimensions in archaeological teeth and bones or characterizing new soft materials for restoration and conservation.
