✦ Synopsis
Polymer additives were extracted with supercritical carbon dioxide and collected in a microtrap. The collected samples were separated by microcolumn liquid chromatography. Polymer samples down to the sub-milligram level were handled without loss of extract. Information about the distribution of additives was also obtained.
