Popis: The chemical characterization of organic residues found in association With ceramic vessels can provide direct information on original vessel use and on diet and cooking practices of people in the past. Major improvements in analytical instrumentation have enabled the study of ever smaller samples of complex organic materials on a molecular level. Various analytical techniques have been applied to study the chemical Composition of organic residues. Volatile, non-chemically bound classes of compounds such as lipids and terpenoids have been selectively extracted and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Other studies have been directed at the characterization of the condensed matrix of solid organic residues (for example, carbonized or cross-linked compounds). Non-destructive Techniques such as nuclear magnetic resonance spectroscopy (NMR) and Fourier transform infrared spectroscopy (FTIR) have been used to characterize materials based on the absence o...
