Hilic mechanism
WebDescription. Hydrophilic interaction liquid chromatography, or HILIC, is a powerful mode of liquid chromatography (LC)that uses polar stationary phases and high-organic initial … WebAug 15, 2013 · It is also important to notice that the ion-exchange mechanism, always present with HILIC phases, plays a major role for the retention of peptides. Based on my own experience, I would indicate that 95% of peptides can be adequately analysed in HILIC thanks to the ion-exchange contribution.

WebHILIC provides the advantage of retaining highly polar analytes 1-3 that are difficult to separate on reversedphase columns such as C18. Simple sugars are well suited for this type of chromatography due to their polar nature. Silica bonded with an aminopropyl silane is a popular phase for HILIC separation of sugars. WebThis HILIC mechanism describes the process of preferential solvation of the polar stationary phase with the aqueous component of the mobile phase, and subsequent depletion of the …
WebDec 2, 2015 · For this reason, hydrophilic interaction chromatography (HILIC) separation mechanisms have been used extensively as an alternative separation mode, spurring the development of zwitterionic … WebMay 10, 2024 · In this study, five kinds of HILIC stationary phases (amino, imidazole, amide, pyridine and zwitterionic) were investigated. It was found that only amino and imidazole columns exhibited the separation of inorganic anions under HILIC conditions. The retention mechanism was further investigated under both columns.
Hydrophilic interaction chromatography (or hydrophilic interaction liquid chromatography, HILIC) is a variant of normal phase liquid chromatography that partly overlaps with other chromatographic applications such as ion chromatography and reversed phase liquid chromatography. HILIC uses hydrophilic stationary phases with reversed-phase type eluents. The name was … WebNational Center for Biotechnology Information
WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Simply put, HILIC is a normal-phase type of separation but uses reversed-phase type eluents.
