Description
CAPCELL CORE is a polymer-coated type core-shell column of 2.7-µm particle with 1.7-µm solid core and 0.5-µm porous layer. CAPCELL CORE provides high-speed and improved separation in UHPLC as well as conventional HPLC.
CAPCELL CORE is a column with minimized undesirable secondary effect of the silanols by applying polymer coating on the surface of core-shell base material. CAPCELL CORE phase is developed by aiming fully to the high-performance separation derived from the unique structure of core-shell.
Features
-
High-efficient separation with lower back pressure
It is known that the separation efficiency (Number of Theoretical Plate, NTP) increase in response to the downsizing of the particle size, which whereas generate high back pressure. And now, the separation impedance is improved by core-shell CAPCELL CORE with similar high efficiency to those of sub 2-m porous particles under a lower back pressure. CAPCELL CORE is suggested the best way to gain highest column efficiency at fast analysis in conventional HPLC.

-
Excellent stability under acidic and basic conditions (pH1.5-10)
Polymer coating technology applied on Capcell Core leads to an excellent stability under acid and basic conditions. Clear differences from other core-shell products can be observed.
