Abstract
An on-chip packed reactor bed design is disclosed that allows for an effective exchange of packing materials such as beads at a miniaturized level. Also disclosed is a method of treating a sample within a microfluidic analysis system, comprising; providing a main channel having a trapping zone; providing a slurry of a reagent treated packing material; inducing a flow of said packing material into said trapping zone through a flow channel connected to said trapping zone to load said trapping zone and form a packed bed of said packing material; and flowing a sample containing analytes through said packed bed, said reagent treating the sample. The present invention extends the function of microfluidic analysis systems to new applications including on-chip solid phase extraction (SPE) and on-chip capillary electrochromatography (CEC). The design can be further extended to include integrated packed bed immuno- or enzyme reactors.
