AbstractIn this work, a novel kind of particulate capillary precolumns with double-end polymer monolithic frits has been developed. Firstly, the polymer monolithic frit at one end was prepared via photo-initiated polymerization of a mixture of lauryl methacrylate and ethyleneglycol dimethacrylate with 1-propanol and 1,4-butanediol as porogens and 2,2-dimethoxy-2-phenylacetophenone as a photo-initiator in UV transparent coating capillary (100 mu m i.d.). Subsequently, C18 particles (5 mu m, 100 angstrom) were packed into the capillary, and sealed with the polymer monolithic frit at another end. To prevent the reaction of monomers and C18 particles, the packed C18 particles were masked during UV exposure. The loading capacity of such a precolumn was determined to be about 9 mu g by frontal analysis with a synthetic peptide APGDRIYVHPF as a model sample. Furthermore, two parallel precolumns were incorporated into a two-dimensional nano-liquid chromatography (2D nano-LC) system with dual capillary trap columns for peptide trapping and concentration. Compared to 2D nano-LC system with a single trap column, such two dimensional separations could be operated simultaneously to improve the analysis throughput. All these results demonstrated that such capillary precolumns with double frits would be promising for high-throughput proteome analysis.
