Method for solid-phase extraction using a porous monolith

Abstract

A method for solid-phase extraction and/or separation of one or more compounds of interest from a liquid sample which including: integrating a self-supporting porous monolith in a fluid duct wherein the self-supporting porous monolith is stationary in the fluid duct during the method and forms a filter in the fluid duct; passing the sample at least once through the porous monolith in the fluid duct over at least one portion of the porous monolith, the self-supporting porous monolith having a largest dimension less than or equal to 3 mm transverse to the fluid duct, the fluid duct having one or more open ends prior to integration, the or at least one of the ends remaining open during the step of integrating the porous monolith.
