Separation Mechanisms in Hydrophilic Interaction Chromatography
Hydrophilic interaction chromatography (HILIC) is a technique that has become increasingly popular for the separation of polar, hydrophilic, and ionizable compounds, which are diffi cult to separate by reversed phase chromatography (RP) due to their poor retention when RP is used. HILIC typically uses a polar stationary phase such as bare silica or a polar bonded phase, together with an eluent ...
متن کاملA comparative study of electrostatic repulsion-hydrophilic interaction chromatography (ERLIC) versus SCX-IMAC-based methods for phosphopeptide isolation/enrichment.
Electrostatic repulsion-hydrophilic interaction chromatography (ERLIC) has been introduced recently for phosphopeptide enrichment. Here we compared ERLIC with the well-established SCX-IMAC for identifying phosphopeptides in EGF-treated A431 cells. The ERLIC approach detected a higher number of phosphopeptides (17 311) than SCX-IMAC (4850), but it only detected 926 unique phosphopeptides compare...
متن کاملHydrophilic interaction chromatography reduces the complexity of the phosphoproteome and improves global phosphopeptide isolation and detection.
The diversity and complexity of proteins and peptides in biological systems requires powerful liquid chromatography-based separations to optimize resolution and detection of components. Proteomics strategies often combine two orthogonal separation modes to meet this challenge. In nearly all cases, the second dimension is a reverse phase separation interfaced directly to a mass spectrometer. Her...
متن کاملHydrophilic interaction liquid chromatography (HILIC)—a powerful separation technique
Hydrophilic interaction liquid chromatography (HILIC) provides an alternative approach to effectively separate small polar compounds on polar stationary phases. The purpose of this work was to review the options for the characterization of HILIC stationary phases and their applications for separations of polar compounds in complex matrices. The characteristics of the hydrophilic stationary phas...
متن کاملHydrophilic interaction chromatography
In the early 1990s, hydrophilic interaction (liquid) chromatography (HILIC) emerged as a new separation method. HILIC is becoming increasingly popular for the separation of polar compounds in aqueous-organic mobile phases rich in organic solvents (usually acetonitrile). It has become important for the separation of pharmaceuticals, neurotransmitters, nucleosides, nucleotides and other compounds...
