Chromolith® Prep monolithic stationary phases are new ultra-pure silica phases, which gain their special properties from a bimodal pore structure. This structure is a property of a new 'Sol-Gel' technology and consists of macropores and mesopores. The mesopores with an average diameter of 12 nm, form the fine porous structure of the column interior and create a very large surface area on which adsorption of the target compounds occurs.
To operate a monolithic column it is necessary to ensure that no flow-through occurs in the wall region. Therefore the monolith is cladded with a polymeric material (special PEEK) and can be connected directly to each HPLC system and used as 'ready to use' column.
