| 20110024356 | SEPARATION CARTRIDGES AND METHODS FOR FABRICATION AND USE THEREOF - Embodiments of the invention provide separation cartridges, methods for fabricating separation cartridges, and methods for using separation cartridges. One aspect of the invention provides a separation cartridge including a first end, a second end, and one or more sorbents located between the first end and the second ends, the one or more sorbents arranged from the first end to the second end in order of increasing hydrophobicity. Another aspect of the invention provides a method of creating a separation cartridge having varying hydrophobicity. The method includes loading a filtration material and a cross-linking agent into a cylinder and selectively exposing the material to an energy source to selectively initiate a cross-linking reaction within the filtration material. | 02-03-2011 |
