An important part of GCI scientific research is developing analytical technologies that can provide more comprehensive information regarding works of art and their condition. The Institute studies analytical techniques and strategies for application to conservation, and works to introduce them into the field through training, workshops, field projects, and publications. The subjects of analytical study vary—from canvas and panel paintings to building materials. A variety of materials characterization equipment is employed in these studies.
An example of this research at the GCI is the analysis of organic materials using gas chromatography-mass spectrometry (GC-MS). A powerful analytical tool for studying organic substances, GC-MS—widely used in biomedical work and environmental studies—is designed to identify the components of complex mixtures. GCI scientists work to advance the state of the art in GC-MS analysis of organic materials, incorporating new technological developments, extensive use of quantitative analysis, and improved data-interpretation techniques. Because organic materials are used so extensively in the creation of art, this analytic technique can provide significant information for conservators.
Current projects with components that have advanced the development of analytical technologies include:
