WebDec 1, 2016 · Although HILIC SPE is efficient (reproducible and sensitive) for glycopeptide enrichment from mixtures, hydrophilic non-glycosylated peptides are also frequently co-enriched. This represents a particular problem for analysing complex samples as the co-enriched hydrophilic peptides can cause glycopeptide ion-suppression. WebInteraction liquid chromatography (HILIC) SPE has extensively been applied due to its low bias towards different glycan types [6,7]. In contrast to the normal phase liquid chromatography, the HILIC retention mechanism is mainly a based on the hydrophilic partitioning of the analyte to the water enriched surface

"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. " - Hilic spe
