Abstract

See full text

A method and apparatus involving the configuration of an open capillary channel for size-based separation of analytes is described. The open capillary channel contains numerous turns of defined angles separated by intervening linear or curvilinear segments of capillary tubing. The configuration of the channel allows analyte differentiation based on diffusion coefficients and thus separates analytes by size.
