Abstract
A capture and purification apparatus is configured as a stand-alone apparatus or as part of a larger system. The capture and purification apparatus can be configured as a microfluidic cartridge that includes microfluidic circuitry and individually controlled valves. The microfluidic cartridge can be configured to function independently, or can be configured to be coupled to a separate instrument that provides the actuation to perform the capture and purification process. The capture and purification apparatus is configured as a volume-driven system that applies single-direction valves, a single fluid driving device, and fluid lines to control and discretely direct fluid flow within a full-loaded fluidic system. Such control enables various fluid sample processing techniques to be performed including, but not limited to, lysis, thermal cycling, and/or target analyte capture and purification, for example using a combination of ion-exchange chromatography and size-exclusion chromatography (SEC).
