Abstract:
1. A split thin-flow separations device, comprising: a) a fluid channel having an inlet zone, an outlet zone, and a transport region between the inlet zone and outlet zone, said inlet zone including a sample inlet and a carrier fluid inlet which are fluidly separated by an inlet splitter to minimize mixing of fluids from respective inlets in the inlet zone, said transport region being a substantially open rectangular ribbon channel having a sample wall opposite a carrier wall and two side walls bridging the sample wall and carrier wall, said two side walls having a height substantially less than a width of each of the sample wall and carrier wall, so as to form an inlet fluid rich region proximate the sample inlet wall and a carrier fluid rich region proximate the carrier wall, and said outlet zone including a sample outlet and a carrier outlet which are fluidly separated by an outlet splitter to segregate portions of a fluid into each of the two outlets as the fluid enters the outlet zone; and b) at least one cross-flow inducer along a wall of the fluid channel in the transport region, said at least one cross-flow inducer is oriented to direct a cross-flow fluid into the transport region.
