<p>Miniaturized planar column devices (2) for use in liquid phase separation apparatus are described. The devices include microstructures that have been fabricated by laser ablation in a variety of novel support substrates. Devices formed according to the methods of the invention include associated laser-ablated features required for function, such as on-device reservoirs (16) or makeup flos compartments, analyte detection means and sample injection means. The miniaturized columns can be used in an apparatus intended for analysis of either small and/or macromolecular solutes in the liquid phase which employs chromatographic electrophoretic, electrochromatographic separation means. The apparatus can include a variety of optional injection means, manifolds, keeper means, post column collection means, and combinations thereof.</p> |
