Convective Interaction Media® (CIM) disk monolithic columns are specific among the chromatographic columns because of their monolithic structure and extremely short column length. In this work, HETP values and Z factors for different groups of molecules—proteins, DNA, oligonucleotides, peptides, and organic acids on strong anion exchange CIM disk monolithic columns were determined. Results are discussed in terms of the molecule structures and applied to develop different approaches for successful separation of abovementioned group of molecules on these types of columns.
