The demand for faster, greener, more cost effective processes is of great important across all industries including chemical pharmaceutical and petrochemical sectors. As a result the key driver of chromatographic research is addressing these demands. The ultimate goal in liquid chromatography is “The best separation in the shortest time”. While sub 2µm fully porous particle stationary phases have addressing this demand for faster more efficiency separations, a research focus which has recently seen a resurgence has been core-shell particle technologies which offer similar performance to sub 2 µm particles without the added back pressure requirements of sub 2 µm fully porous particles.
