WebSeQuant ® HILIC (hydrophilic interaction liquid chromatography) HPLC columns constitute a range of high-performance tools for separating polar hydrophilic compounds. All columns carry densely bonded, truly zwitterionic functional groups with a charge balance of 1:1. 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.
