FAST ANALYSIS OF MODERN OIL PAINTINGS AND DYES IN TEXTILES BY SURFACE ACOUSTIC WAVE NEBULIZATION-MASS SPECTROMETRY (SAWN-MS)

摘要

GC-MS and LC-PDA are the methods of choice to study the binding media of paintings and dyes in textiles [1,2]. Relatively large samples are needed and long sample preparation and analysis time. In GC-MS, limited information is obtained due to the hydrolysis and derivatization steps, the high temperatures and ionization energies used. SAWN-MS maintains the integrity of fragile molecules due to mild ionization, greatly reduces the sample sizes and the analysis time.
