Agilent Polaris C8-A HPLC Columns

Agilent Polaris C8-A HPLC columns provide alternative selectivity for general polar applications and are designed with hydrogen-bond accepting endcapping. The C8-A phase offers reduced retention of hydrophobic compounds compared to the C18-A column. Excellent retention is observed under highly aqueous conditions while avoiding phase collapse and shifting retention times. Manufactured with fully porous silica in 3 µm for higher resolution HPLC methods or 5 µm for traditional HPLC applications.
