Due to its morphology core-shell (solid core or fused core) particles lead to greater efficiency compared to entirely porous particles of a similar size. The new CORTECS HPLC columns by Waters make a relevant step towards innovative levels of efficiency especially in UPLC®. Analytics-Shop.com is an independent merchant of high quality chromatography products and the only distributer of CORTECS HPLC columns in Germany.
These HPLC columns have a non-porous solid inner core that is coated with a porous separating phase. For almost 40 years this method has been used in chromatography to accelerate the transfer of big particles (> 40 µm) and to counteract wider peaks. So separations can be carried out faster and more efficiently. For a long time small sized and regular in shape particles have been considered the relevant part. Over the years particle size came down to sub-2µm which enabled high speed analysis.
Selectivity, compared to efficiency, can have an even bigger impact on differential solutions since often several modifications to phases are tested at the same time. The whole selection of CORTECS products is available at Analytics-Shop.com from now on. Here, clients certainly find various other core-shell materials such as Poroshell from Agilent, Nucleoshell from Macherey-Nagel or AccuCore from Thermo Scientific. Our HPLC Column Configurator helps to easily select the exact right column from more than 60 000 columns at Analytics-Shop.com. By adding the innovative and highly efficient CORTECS columns to its product range, Analytics-Shop.com keeps on offering a selection of high quality products according to latest technology and the needs of modern laboratories.
