Based on ultra-pure Silica gel zwitterionic HILIC phases are ideal for the analysis of polar and ionizable compounds. Stronger interaction of more polar compounds with stationary aqueous layer.
Faster elution of nonpolar compounds is possible due to minor hydrophobic interactions. Retention increases with the charge of the analyte.
