Abstract
A chromatographic column assembly is described, comprising a channel and a flow inducer. The channel comprises an inlet for receiving a sample liquid and an outlet, and is adapted for separating the sample liquid into components when the sample liquid flows through the channel in an axial direction from the inlet to the outlet. The flow inducer is adapted for controllably inducing, when the sample fluid is flowing through the channel, a motion of the sample liquid in the channel in a plane substantially orthogonal to the axial direction.

A chromatographic column assembly comprising:
- a channel comprising an inlet for receiving a sample liquid and an outlet, the channel being adapted for separating the sample liquid into components when said sample liquid flows through the channel in an axial direction from said inlet to said outlet;
- and
- a controllable flow inducer configured to electrically induce, when the sample fluid is flowing through the channel, a motion on charged and/or polarizable constituents of said sample liquid in the channel in a plane orthogonal to said axial direction, the electrically induced motion consisting of motion orthogonal to the axial direction.
A liquid chromatography method for separating a sample liquid, the method comprising:
- generating a flow in an axial direction of the sample liquid through a channel;
- separating the sample liquid into a plurality of components by mass transfer interactions in the channel;
- and
- controllably electrically inducing a flow in the sample liquid, when the sample liquid is flowing through the channel,
- wherein said controllably electrically inducing of the flow comprises inducing a motion on charged and/or polarizable constituents of the sample liquid in the channel in a plane orthogonal to the axial direction, the electrically induced motion consisting of motion orthogonal to the axial direction.
