Agilent Polaris C18-Ether HPLC columns are endcapped with an ether group to create a more polar surface for selectivity variation. These polar-optimised columns utilise ultra-high purity silica to minimise silanol activity, while the novel polar modified technology maximises polar retention when using highly aqueous mobile phases. Featuring fully porous silica in either 3 µm for higher resolution HPLC methods, or 5 µm for proven and reliable HPLC applications.
Features
- C18 stationary phase with ether endcapping for a more polar surface for alternative selectivity
- Excellent retention under aqueous conditions while avoiding phase collapse and shifting retention times
- 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-A and C18-Amide for alternative selectivity, and C8-A and C8-Ether for reduced retention of hydrophobic compounds
