Abstract
AbstractMolecular weight distributions generated by pulsed‐laser polymerization have been determined experimentally using multi‐detector size exclusion chromatography (SEC). The conditions for accurate and precise SEC have been defined. The importance of the inter‐detector delay (IDD) is stressed and two different methods of defining IDD are compared. In addition this work highlights the problems associated with the use of Mark‐Houwink constants in constructing a universal calibration curve. Some preliminary results obtained from matrix‐assisted‐laser‐desorption‐ionisation mass spectrometry are also presented.
