IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishDuring the last decade, column manufacturers have put much effort into the design and preparation of materials (e.g., sub-2 micron fully porous and core-shell particles) suitable for highly efficient and fast separations in ultra high-performance liquid chromatography (UHPLC). It is a matter of fact that this advancement has so far only partially touched the field of chiral liquid chromatography. This delay has been essentially due to the lack of understanding of mass transfer processes in chiral chromatography, on the one hand, and to practical difficulties in the preparation of small chiral particles. Recently, Pirkle-type chiral stationary phases (CSPs) have been prepared by using both sub-2 micron fully porous and 2.6 micron core-shell silica particles as base materials. This report describes the employment of these CSPs to achieve not only very high performance but also ultrafast (less than one second) chiral separations in different chromatographic modes.

| Abstract in inglese: | During the last decade, column manufacturers have put much effort into the design and preparation of materials (e.g., sub-2 micron fully porous and core-shell particles) suitable for highly efficient and fast separations in ultra high-performance liquid chromatography (UHPLC).

This delay has been essentially due to the lack of understanding of mass transfer processes in chiral chromatography, on the one hand, and to practical difficulties in the preparation of small chiral particles. Recently, Pirkle-type chiral stationary phases (CSPs) have been prepared by using both sub-2 micron fully porous and 2.6 micron core-shell silica particles as base materials.
