A system for high throughput sample preparation and analysis. The system includes a chromatography column including an insoluble matrix. A fluidic circuit is capable of passing a fluid over the insoluble matrix in a first direction such that an analyte in the fluid binds to the insoluble matrix, and back-eluting an elution fluid over the insoluble matrix in a second direction opposite the first direction to output a sample that includes the analyte. A controller controls the fluidic circuit to periodically perform the steps of passing the fluid over the insoluble matrix and back-eluting the elution fluid over the insoluble matrix to output a plurality of samples at a periodic rate.
