CHIRAL ART Coated type

Features

Extended packing durability

CHIRAL ART have outstanding packed bed stability provided by the use of high-strength super-wide-pore silica and innovative packing technology. The column efficiency and selectivity are maintained, even after sequential gradient tests at a high flow rate (three times higher than the normal flow rate) and a high pressure (rapid pressure change).
CHIRAL ART are suitable for the case where one intends to shorten an analysis time, (re-)equilibration time, and/or column cleaning time by increasing the flow rate. This feature is also effective when a highly viscous solvent needs to be used as a mobile phase on immobilized type columns.
