As in the case of all chromatographic methods, the ideal sample introduction method for supercritical fluid chromatography (SFC) would provide a narrow and sharp solvent peak (or no solvent peak), quantitative transfer of the sample into the column, and high reproducibility. Elimination of the solve
A benchtop SFCIMS system is described which utilizes supercritical carbon dioxide in a 50 micron diameter open tubular column interfaced directly to an unchanged commercially available benchtop capillary GCIMS system equipped with a chemical ionization (Cl) source. A small amount of methane reagent
## Abstract The use of small internal diameter precolumns (11โ25โฮผm 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 (3000โ5000 plates m
## Abstract A unified chromatograph was constructed in which open tubular column gas chromatography, at normal helium carrier gas pressures, followed by supercritical fluid chromatography with carbon dioxide mobile phase was carried out in a single run using a 100โฮผm i. d. column. Sample introducti
