RP-LC using Novel CIM® Disk Monolithic Columns
The development of new chromatographic supports with the aim to improve their chromatographic, hydrodynamic and mechanical properties is continually going on.
CIM Convective Interaction Media® monolithic columns represent a new chapter in every mode of the chromatography. Monolithic columns consist of a single piece of a highly porous polymer with a bimodal pore size distribution, forming flow-through channels . Since all of the mobile phase flows through the pores, molecules to be separated are transported to the active sites by convection . Therefore, the entire analysis can be completed in a very short time.
In this work, the performance of novel semi-preparative CIM® RP-SDVB disk monolithic column for separating proteins and peptides has been investigated. Since the column length in the case of gradient separations commonly used for large molecules, does not play a significant role, CIM® RP-SDVB disk monolithic column are extremely short, typically of only 3 mm. The effect of decreasing column length on the resolution under the conditions of a linear gradient has been presented.
Finally, a 1 minute purification of oligodeoxynucleotide from the synthetic mixture has been performed.
