CHROMATOGRAPHY DEVICE AND METHOD FOR FILTERING A SOLUTE FROM A FLUID
20170349626 · 2017-12-07 ·

A chromatography device for removing a solute from a fluid is provided. The device has a first plate having an inlet and a first channel. The first channel directs the fluid from the inlet towards chromatographic media housed in a chamber coupled to the first plate. The chamber has a leading edge for receiving the fluid from the first channel and a trailing edge for delivering the fluid to a second channel. The chromatographic media is configured to remove the solute from the fluid as the fluid passes through the chamber. The device also has a second plate coupled to the chamber having the second channel and an outlet. The second channel directs the fluid from the chamber to the outlet. The direction of flow of fluid through the first channel and the second channel is transverse to a direction of flow of the fluid through the chromatographic media. A method of removing a solute from a fluid is also provided.
