Hydrophilic 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...
متن کاملOnline coupling of reverse-phase and hydrophilic interaction liquid chromatography for protein and glycoprotein characterization
We have developed a novel system for coupling reverse-phase (RP) and hydrophilic interaction liquid chromatography (HILIC) online in a micro-flow scheme. In this approach, the inherent solvent incompatibility between RP and HILIC is overcome through the use of constant-pressure online solvent mixing, which allows our system to perform efficient separations of both hydrophilic and hydrophobic co...
متن کاملCharacterization of intact neo-glycoproteins by hydrophilic interaction liquid chromatography.
In this study, an HPLC HILIC-UV method was developed for the analysis of intact neo-glycoproteins. During method development the experimental conditions evaluated involved different HILIC columns (TSKgel Amide-80 and ZIC-pHILIC), and water-acetonitrile mixtures containing various types of acids and salts. The final selected method was based on a TSKgel Amide-80 column and a mobile phase compose...
