Abstract: The invention provides novel porous materials that are useful in chromatographic processes, e.g., solid phase extraction, and that provide a number of advantages. Such advantages include superior wetting characteristics, selective capture of analytes of interest, and non-retention of interfering analytes. In certain aspects, the materials feature at least one hydrophobic component, at least one hydrophilic component and a average pore diameter of about 100 Åto about 1000 Å. In certain embodiments the materials also exhibit a nitrogen content from about 1% N to about 20% N. In certain embodiments, the materials also exhibit more than 10% of the BJH surface area of the porous material is contributed by pores that have a diameter greater than or equal to 200 Å. The invention advantageously provides novel porous materials having a large percentage of larger pores (i.e. wide pores). The invention advantageously provides novel porous materials that overcome the problems of SPE of biological samples.
