Direct inlet mass spectrometry for a rapid characterization of indigo in lipidic and proteinaceous matrices
Direct inlet mass spectrometry (DI-MS) was examined for its suitability to quickly identify indigo in mixtures with lipidic and proteinaceous binders, such as those characteristic of paintings and polychromy. The technique was tested on naturally aged reference mixtures of indigo with linseed oil, r...
