POROUS MATERIALS FOR SOLID PHASE EXTRACTION AND CHROMATOGRAPHY AND PROCESSES FOR PREPARATION AND USE THEREOF

摘要

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. 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.
