C.) from the Metropolitan Museum of Art in New York City; a silk tapestry (1540s) from the Fontainebleau Series, Kunsthistorisches Museum, Vienna, Austria; a silk textile from Istanbul (1551-1599) from the Textile Museum, Washington, D.
Moreover, bubble formation due to redox reactions of water at the electrode does not effect CE/ESI-MS performance, because the actual metal/liquid contact occurs outside of the CE capillary.
Now, for the first time, scientists at the Smithsonian's Museum Conservation Institute have developed a fast and reliable method to date silk.
The new method uses the natural deterioration of the silk's amino acids--a process known as racemization--to determine its age.
The Smithsonian Museum Conservation Institute team used fiber samples taken from a series of well-dated silk artifacts to create a chart of left-hand and right-handed amino-acid calibration ratios against which other silks fabrics can be dated.
Those items included new silk fibers; a silk textile from the Warring States Period, China (475-221 B.
