Fused-silica capillaries of I.D. of 5, 10 and 25 pm were coated with PS-255 or PS-264 in order to achieve highly efficient columns for reversed-phase open-tubular liquid chromatography. Various coating solvents were tested, of which Freon-l 14 showed the most promising features with respect to spee
