BAKERBOND Q2100 columns – Phase Guide

C18: A “workhorse” column. Separates analytes through hydrophobic interactions.

C8: Separates analytes through hydrophobic interactions. Suitable for analytes that are too retentive on a C18 column.

Phenyl-Hexyl: Exhibits different selectivity to C18 & C8 phases.  Suitable for the analysis of aromatic compounds and analytes with electron withdrawing groups such as halogens, nitro groups, ketones, esters, and acids.

Sil: Can be used in both reversed and normal phase modes for the separation of more polar analytes.
