Stationary phase: The material packed within a chromatographic column that interacts differentially with analytes, enabling their separation.

The earliest stationary phases were relatively large particles (40-50 µm) of silica, for normal phase chromatography, and polymers (mainly polystyrene-divinylbenzene) or silica with coatings of a ...

Countercurrent chromatography systems were tested and combined to optimize their capacity for handling non-polar and polar substances.

Harry Ritchie, PhD, Director of Business and Market Development at Advanced Materials Technology, shares how crucial ...

New equipment and methodology for the continuous separation and purification of chemical species via continuous liquid–liquid partition chromatography are presented. This is achieved by cascading ...

Abstract The peak-production rate (peak capacity per unit time) in comprehensive off-line two-dimensional liquid chromatography (LC/×/LC) was optimized for the separation of peptides using poly ...
