Abstract

The use of small internal diameter precolumns (11–25‐μm i. d.) helped solute focussing when using solvent vent sample introduction in open tubular column supercritical fluid chromatography (SFC). Column efficiencies were similar to those obtained with split injection (3000–5000 plates m^−1^). Trace analysis in SFC was improved because large volumes (1 μL) could be introduced for analysis with little sacrifice in column efficiency.
