## Abstract Recent advances in techniques for the packing of microcolumns of down to 50 ΞΌm inner diameter using supercritical CO~2~ have led to rapid growth in the use of high efficiency packed capillary columns in SFC. Maximization of the usefulness and applications of these techniques requires gr

## Abstract The need for mixed mobile phases at low flow rates suitable for capillary and packed capillary supercritical fluid chromatography (SFC) has led to the use of an air actuated high pressure prime/purge valve for on‐line modifier introduction. This valve can consistently deliver small amou

## Abstract A new method to accurately deliver small amounts (0.5 to 20 mol%) of modifier into CO~2~ was used to study the effects of three different modifiers (methanol, water, and formic acid) in packed capillary column SFC. The method allows the use of different modifiers, with minimal instrumen

## Investigations have been initiated to examine the basic elements of resolution and how they vary individually and collectively in terms of modifiers used in supercritical fluid chromatography (SFC). Capacity factors ( k ) have been determined for a mixture of polynuclear aromatic hydrocarbons f
