Abstract: The present invention relates to a flow-through device comprising at least one separation column wherein a first packing component, which comprises particles of alumina and/or silica, and a second packing component, which comprises a powder of one or more hygroscopic salts are provided. The two packing components may be blended or layered in the device, which may comprise a single tube or a plurality of tubes arranged in a plate format, such as the wells of a multiwall plate or tubes in a rack. In addition, the invention relates to a method for removing one or more matrix components, such as pigments, from a biological sample, by passing said sample across a first packing component, which comprises particles of alumina and/or silica, and a second packing component, which comprises a powder of one or more hygroscopic salts.

Abstract: Disclosed is a method for equilibrating a chromatography column including the steps of (i) providing a mobile phase; and (ii) passing the mobile phase through a packed chromatography column; wherein the mobile phase includes two liquids, the proportions of which change as it is passed through the column. Also discussed are automated aspects of the method, as well as a system capable of performing such method.

Abstract: Methods and systems for improving a presentation function of a client device based on feedback data indicative of presentation effectiveness are disclosed. A server transmits, over a communication network, a first instruction that configures the client device to provide a first presentation via a user interface to an individual. The server receives physiological data collected by one or more sensors of the client device and associated with the individual and the first presentation. Based on feedback data, including the received physiological data, representative of behavior change subject to the first presentation, the server computes an effectiveness assessment of the first presentation.

Abstract: The present invention relates to a phase separation element and a phase separation device comprising such a phase separation element, which may be used for separating a biphasic aqueous and organic liquid system irrespective of which liquid is heavier.

Abstract: A carpet locating and retaining system for a vehicle and a method of using the same having a head portion and a body portion. The device further includes retaining means for retaining the device within an aperture formed in the vehicle and fastener receiving means for receiving a fastener therein. The device eliminates the need for a separate locator for the carpet and a retaining system for a cover plate.
