A Tip for Preparing Robust and Consistent Mobile Phases

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 ...

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.
