Guest columnist Matt Przybyciel reviews the structure, behaviour and applications of both alkyl- and phenyl-fluorinated phases in HPLC. The author presents some guidelines on potential areas of application for alkyl and phenyl-fluorinated phases, in which conventional C8, C18 and phenyl phases might have insufficient selectivity or too strong retention.

Fluorinated HPLC Phases — Looking Beyond C18 for Reversed-Phase HPLC

Continued from last month, this month's column discusses specially designed columns for use in highly aqueous environments. Many of these columns also can be used as regular reversed-phase columns for a range of mobile phases.

Columns for Reversed-Phase LC Separations in Highly Aqueous Mobile Phases

The authors suggest ways to avoid phase collapse and regenerate collapsed phases.
