Abstract:
1. A method of preparing a monolithic chromatography column comprising the steps of: providing a carbon monolith precursor having a particulate, porosity-generating fugitive phase dispersed therein, said precursor comprising at least one carbonizable polymer, and said fugitive phase comprising mesoparticles and macroparticles; heating said carbon monolith precursor to carbonize said carbon monolith precursor and form a porous carbon monolith and to remove said fugitive phase therefrom via thermal decomposition and/or volatilization and leave the porous carbon monolith with a hierarchical pore structure of macropores having a size ranging from 0.05 μm to 100 μm and mesopores having a size ranging from 18 Åto 50 nm; and encapsulating said porous carbon monolith within a cladding material conforming to the shape of said porous carbon monolith to form a chromatographic column.
