ABSTRACT:
A device for sample analysis includes a microfluidic device for separating analytes of a sample comprising a liquid, the microfluidic device comprising a substrate having a first surface and a second surface opposite the first surface, the substrate defining features that collectively occupy an area of the substrate of about 0.1 to 10 cm2, the features comprising a sample input port located at the first surface; a drying agent input port located at the first surface; an enrichment column; a separation column; switching ports located at the second surface; and fluid-conducting passages extending through the substrate from the switching ports to the sample input port, the drying agent input port, the enrichment column and the separation column. Also provided are methods and systems for separating analytes from a sample.
