Studying the stratigraphy in paintings and composite objects by applying a micrometrical resolution to measure thickness layers and to evaluate detachments and micro-fractures. NMR profilometry is applied to perform in situ analysis on mural paintings, easel paintings, wood and cellulose based manufacts, polymers, and lapideous materials.
Portable Nuclear Magnetic Resonance (NMR-MOUSE) is an instrument available at MOLAB to perform in situ analysis on mural paintings, easel paintings, wood and cellulose based manufacts, polymers, and lapideous materials. The analysis can be performed from the surface up to 1 cm in depth in a non-invasive way. The main applications are: Measuring water content and moisture (2D mapping). Studying the stratigraphy in paintings and composite objects by applying a micrometrical resolution to measure thickness layers and to evaluate detachments and micro-fractures. Evaluating consolidating, protective and cleaning products. Measuring open porosity, tortuosity and porosity distribution in porous materials. Evaluating and mapping the degree of degradation and physical-chemical properties. Measuringdiffusion and transport of solvents in paintings, gels and porous materials.
