ABSTRACT:
A miniaturized total analysis system (".mu.-TAS") comprising a miniaturized planar column device is described for use in liquid phase analysis. The .mu.-TAS comprises microstructures fabricated by laser ablation in a variety of novel support substrates. The .mu.-TAS includes associated laser-ablated features required for integrated sample analysis, such as analyte detection means and fluid communication means. .mu.-TAS constructed according to the invention is useful in any analysis system for detecting and analyzing small and/or macromolecular solutes in the liquid phase and may employ chromatographic separation means, electrophoretic separation means, electrochromatographic separation means, or combinations thereof.
