High precision vapor phase sampling valves under computer control were used to study the effect of sample size on chromatographic peak shapes and diffusion phenomena in open tubular and wall-coated open tubular columns. Molecular diffusion is treated in terms of axial and Taylor diffusion and velocity profiles are interpreted in terms of the data. Secondary flow effects are considered in detail and are shown to be negligible for these columns compared to molecular, radial, and viscous diffusion. |
