Analysis of egg lipids and their oxidation products by MALDI-FTMS

It is well known that the environment in museums and storage facilities affects the quality of the objects of art stored. The effects of temperature, relative humidity, and light intensity have already been studied on a macroscopic level. However, the chemical quality of the museum atmosphere is not only determined by these physical factors, but also by concentrations of air contamination that diffuse into the museum such as nitrogen oxides and sulphur oxides. Hence, in the current research, egg based binding media are exposed to extreme conditions such as high concentrations of nitrogen oxides and sulphur oxides and high light intensities to investigate the molecular changes.
