Polaris C18-Ether

by Varian

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.
