An innovative monolithic zwitterionic stationary phase for the separation of phenolic acids in coffee bean extracts by capillary electrochromatography
A methacrylate based monolith, containing the innovative zwitterionic monomer (3-allyl-1-imidazol) propane sulfonate, was prepared in 100 µm I.D. silica capillaries by UV initiated photo-polymerization. Composition of the porogen, i.e. a mixture of 1-propanol, 1,4 butanediol and water, was of great...
