Abstract
A separation column for use in a separation process such as chromatography, electrochromatography and electrophoresis is described. The separation column includes multiple collocated monolith support structures and interconnected channels defined by the support structures. The monolith support structures and interconnected channels are created on a substrate using an isotropic etching. The separation column also includes a cover plate disposed on the etched surface of the substrate, creating an enclosed separation column.
