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 ... WebAug 12, 2011 · Hydrophilic interaction liquid chromatography (HILIC) is here successfully coupled to negative-ion electrospray ionization time-of-flight mass spectrometry (ESI-TOFMS) for the analysis of synthetic and chemically modified oligonucleotides.
