The Journal of Microcolumn Separations is a bimonthly international publication established to present original fundamental and applied research concerning all aspects of microcolumn separation methods including microcolumn liquid chromatography capillary electrophoresis microcolumn supercritical fluid chromatography capillary gas chromatography and other related microcolumn techniques. Coupled systems and ancillary techniques particularly in the area of detection are within the scope of the journal. Analytical extraction and sample preparation techniques such as supercritical fluid extraction solid phase extraction membrane sampling and other micro-extraction techniques are also included because of their importance as an integral part of the total analysis. Issues contain scholarly research papers short communications or notes and timely reviews. The Journal of Microcolumn Separations is unique among other journals in that the focus is restricted to microcolumn separation techniques. Other established chromatography journals emphasize gas chromatography or liquid chromatography while this journal emphasizes the miniaturization of all chromatographies and electrically-driven separation techniques. The title and scope of the journal have been designed to accommodate variation of these established microcolumn methods as well as new microcolumn separation methods that are on the horizon. Current trends predict that the most exciting future developments in separation science will be in the areas involving miniaturized systems.
