摘要：
The study presents the possibility to use gel permeation chromatography (GPC) with atmospheric pressure chemical ionization (APCI)-mass spectrometry (MS) for the analysis of oligomeric structures having molecular weights up to 2000gmol(-1). Polymethylmethacrylate and polystyrene oligomers were analyzed in chloroform using 2.1-mm-internal diameter GPC columns. The low flow rate of 50 mu Lmin(-1) and the ionization with chlorine allow a fast optimization of the method parameters. Excellent correlation with the expected isotope distributions and linear calibration curves were obtained for both types of oligomers.
