Hilic phase
WebHILIC uses the same mobile phases and systems as the more common reversed-phase liquid chromatography (RPLC). However, it employs a polar stationary phase to separate potentially problematic polar analytes and retain charged compounds, including inorganic salts.

WebHILIC (Hydrophilic Interaction Liquid Chromatography) is not a new mode of separation, but rather a variation of normal phase liquid chromatography (NPLC), in which sample components distribute between a polar stationary phase and a less polar mobile phase. WebHILIC method development workflow. Understanding the physico-chemical properties of an analyte is essential to the selection of a suitable HILIC column. A combination of log P, …
WebJun 11, 2024 · HILIC chromatography involves not only hydrophilic partitioning but potentially also hydrogen bonding, ion exchange (analyte / stationary phase), more ion exchange (salt additives / stationary phase), ionic (charge) repulsion and ion exclusion (displacement) mechanisms.

WebHILIC is an alternative HPLC mode for separating polar compounds. • HILIC employs conventional polar stationary phases such as silica, amino, or cyano. • A typical mobile phase for HILIC includes water-miscible polar organic solvents such as acetonitrile, acetone, isopropanol, and methanol. •
WebHILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in nature (> 60-70% … bit the bullet phraseWebLike Normal Phase Chromatography, HILIC uses a polar stationary phase and a non-polar yet water-miscible mobile phase. It uses designed stationary phases instead of bare alumina or silica particles. HILIC fills a need in analytical separations and is used for the separation of very polar molecules like acids, bases, and zwitterions. bit theatre aurora ilWebHILIC is a particularly useful separation mode for polar organic compounds that are poorly retained by reversed phase.
