Agilent Polaris C8-Ether HPLC Columns

Agilent Polaris C8-Ether HPLC columns are endcapped with an ether group to create a more polar surface for selectivity variation. The C8-Ether phase offers reduced retention of hydrophobic compounds compared to the Polaris C18-Ether column. The novel polar modified bonding technology maximises polar retention and prevents phase collapse when using aqueous mobile phases. Manufactured with ultra-high purity silica to minimise silanol activity in either 3 µm for higher resolution HPLC methods, or 5 µm for traditional HPLC applications.
