WebWith HILIC methods, the high concentration of organic solvent in the mobile phase raises the pH, and the actual eluent pH can be 1–1.5 units higher than in the aqueous portion alone. The charge state of the column itself can also be affected. WebWhat is HILIC? •HILIC - Hydrophilic Interaction Chromatography •HILIC is a variation of normal-phase chromatography •Stationary phase is a polar material such as silica, cyano, amide, etc. •A high organic-low aqueous mobile phase • i.e. water is the elution solvent •Mechanism is a combination of weak cation exchange

WebHILIC is generally recommended for compounds with negative log P values. Another important analyte parameter is the pK a (-log K a) value; K a gives us an indication of the acidity of a molecule. The larger the pK a value, the weaker the acid. log D provides a good indication of the ionization state of a compound in solution at a specific pH. WebThis effect appears mainly when HILIC and RPLC are coupled as the weak solvent used in HILIC is a strong eluent solvent in RP, and vice versa, leading to poor focusing of the analytes in the 2 D column head. One of the most frequently employed strategies to eliminate this incompatibility is online dilution with a weak solvent using trapping ... g by giuliana facebookWebNew Agilent InfinityLab Poroshell 120 HILIC chemistries combine innovative particle technology and bonded phases to improve retention and peak shape for polar analytes.
