In 1989 the Getty Conservation Institute's scientific program began developing methodologies to identify binding media in paint. Initial efforts focused on the use of advanced instrumentation; however, recognizing the need for low-tech, low-cost, and user-friendly methods, the Institute developed a kit using medical diagnostic technology for identification of the major binding media types encountered during the conservation of ethnographic art objects. The project also developed and improved thin-layer chromatography tests for detecting binding media components.
Also researched were other methods for analyzing binding media, including the following: advancing the use of infrared microscopy for the study of painting cross sections; analytical strategies for differentiating similar proteinaceous bindings; using an elemental analyzer for determination of carbon, hydrogen, nitrogen, and sulfur in binding media samples; and using a separation process in combination with gas chromatography-mass spectrometry to identify major and minor components of a small paint sample. The total outcome of this research contributed to the development of a methodology for radiocarbon dating of paint layers.
