New techniques for liquid chromatography in open-tubular columns.
Methods for sample introduction, capillary column fabrication, and on-column detection are discussed. A new cross-linked polymer stationary phase coating (based on similar coatings for capillary gas chromatography) is described. Results of separations of urinary components using 16-mum open-tubular columns and electrochemical detection and laser-induced fluorescence detection are shown.
