A micro-machined frit is provided for use in a chromatography column, having a substrate with a thickness, and holes extending through the thickness and providing fluid communication through the substrate. A micro-machined flow distributor is provided for use in a chromatography column having a substrate, holes extending through the substrate, and channels in fluid communication with the holes. A micro-machined integrated frit and flow distributor device is also provided having a substrate with a thickness, holes extending through the thickness and providing fluid communication therethrough, and channels in fluid communication with at least one of the holes. A chromatography column is provided having a tube, an extraction medium contained therein, and a micro-machined frit positioned proximate an end of the tube. The column can include a micro-machined flow distributor positioned between the frit and the end of the tube. |
