Polaris™ C18-ether phase has a rapid high resolution separation based on ultra pure silica to which alkyl chains and polar modifications are attached.

• Enhanced retention and peak shape of polar analytes
• Increased retention for basic analytes
• pH range 1,5 to 10

Polaris™ C18-ether offers a different selectivity from C18-A with particular utility for hydrogen bond-donating compounds and typically delivers increased retention of polar compounds away from the void volume.
