Polaris C18
Polaris C18 HPLC Columns from Agilent Technologies
Polaris C18-A is the best starting place for separations where the benefits of polar-modified columns are desired. The polar modifications of C18-A help it avoid poor peak shape and retention issues in low organic conditions. Polaris C18-A columns offer alternate selectivity for general polar applications and are designed with hydrogen-bond accepting endcapping. Available in 3 µm, 5 µm, and 10 µm.
Polaris C18-Ether columns are endcapped with an ether group to create a more polar surface for selectivity variation. Available in 3 µm and 5 µm particle sizes.
Polaris Amide-C18 columns provide subtle alternative selectivity because they do not have steric protection. They utilize an embedded amide, similar to Bonus-RP columns, and are available in 3 µm, 5 µm and 10 µm particle sizes.
