Journal ArticleDOI
Hydrophilic interaction chromatography.
Petrus Hemström,Knut Irgum +1 more
TL;DR: The review attempts to summarize the ongoing discussion on the separation mechanism and gives an overview of the stationary phases used and the applications addressed with this separation mode in LC.
Journal ArticleDOI
Atom-transfer radical graft polymerization initiated directly from silica applied to functionalization of stationary phases for high-performance liquid chromatography in the hydrophilic interaction chromatography mode.
TL;DR: Initiation of atom-transfer radical polymerization of a number of monomers directly from chlorinated porous silica particles has been performed, resulting in a hydrolytically stable initial Si-C bond, tethering the polymer to the silica substrate.
Journal ArticleDOI
Polymer-based monolithic microcolumns for hydrophobic interaction chromatography of proteins
Petrus Hemström,Petrus Hemström,Anna Nordborg,Anna Nordborg,Knut Irgum,Frantisek Svec,Jean M. J. Fréchet +6 more
TL;DR: The porous structures of the monoliths were characterized and their performance was demonstrated with a separation of a mixture of myoglobin, ribonuclease A, and lysozyme under conditions typical of HIC.
Journal ArticleDOI
Alternative organic solvents for HILIC separation of cisplatin species with on-line ICP-MS detection.
TL;DR: Using 1,4-dioxane as solvent in HILIC provides the best compromise between carbon deposition and separation efficiency among a series of high-boiling water-miscible solvents tested.
Journal ArticleDOI
Hydrophilic interaction liquid chromatography (HILIC) coupled to inductively coupled plasma mass spectrometry (ICPMS) utilizing a mobile phase with a low-volatile organic modifier for the determination of cisplatin, and its monohydrolyzed metabolite
TL;DR: In this article, the on-line coupling of hydrophilic interaction liquid chromatography (HILIC) to inductively coupled plasma mass spectrometry (ICPMS) was demonstrated.
