WebHILIC HPLC/UHPLC columns draw and retain a water-enriched layer onto the surface of the silica which facilitates the interaction of polar compounds with the stationary phase for increased retention. ... Using Strata® … Webbeen shown in using the HILIC separation with mass spectrometry detection. A fourfold increase in sensitivity with HILIC mode was produced due to more efficient spraying and desolvation in the ESI-MS source as compared to RPLC. This generated less baseline noise and a more intense MS signal. Figure 3 shows the elution order and selectivity of the
