Agilent Polaris C18-A HPLC Columns

Agilent Polaris C18-A HPLC columns offer alternative selectivity for general polar applications and are designed with hydrogen-bond accepting endcapping. These reversed phase columns ensure excellent retention under aqueous conditions (up to 100%) – while avoiding secondary interactions, phase collapse, and shifting retention times. Manufactured with fully porous silica in 3 µm, 5 µm, and 10 µm particle sizes.

Features

C18 stationary phase with hydrogen-bond accepting endcapping
Best starting place for separations where the benefits of polar-modified columns are desired
Polar modifications of C18-A help it avoid poor peak shape and retention issues in low organic conditions
Compatible with 100% aqueous mobile phase
USP designation of L1
MetaGuards connect directly to the analytical column – no additional holder is required
Polaris range also includes C18-Ether and C18-Amide for alternative selectivity, and C8-A and C8-Ether for reduced retention of hydrophobic compounds
