Polaris C18-Ether

Polaris C18-Ether and Polaris C8-Ether: For Hydrogen Bond Donating Compounds

Outstanding peak symmetry
Increased retention for basic analytes
Unique selectivity

Polaris Ether modified C18 and C8 columns give additional selectivity for compounds that are hydrogen bond donors. Ether columns offer the same phase collapse resistance and silanol shielding as the rest of the Polaris column line.

Polaris C18-Ether

Polaris C18-Ether offers an alternative selectivity to Polaris C18-A and standard C18 phases, and typically delivers increased retention of polar compounds away from the void volume.

Polaris C8-Ether

Polaris C8-Ether offers an alternative selectivity to Polaris C8-A with particular utility for hydrogen bonding compounds.

Similar columns from other manufacturers to Polaris C18-Ether

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated

Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.

A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.

No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
