The Separation of Hexacyanoferrate(II) and Hexacyanoferrate(III) Ions by Reversed-phase Partition Chromatography

The separation of the C12-C18 fatty acids by reversed-phase partition chromatography.

Separation of Somatropin and Its Degradation Products by High-Performance Liquid Chromatography Using a Reversed-Phase Polymeric Column

The accurate prediction of protein stability is one of the most challenging goals in protein formulation and delivery. In this study, a gradient RP-HPLC method is described for the separation of human growth hormone (hGH) variants as deamidated and oxidized forms. The methodology employed a polymeric poly (styrene-co-divinylbenzene) column and a 1mL/min flow rate of a linear gradient of 0.1% v/...

Enantiomeric separation of Linezolid by chiral reversed-phase liquid chromatography.

A chiral liquid chromatographic method is developed for the enantiomeric resolution of Linezolid, (S)(-)-N-[[-3-(3-fluoro-4-(4-morpholinyl)phenyl]-2-oxo-5-oxazolidinyl] methyl] acetamide, an antibiotic in bulk drugs. The enantiomers of Linezolid are resolved on a Chiralcel OJ-RH column using a mobile phase system containing 150mM di-sodium hydrogen phosphate buffer (pH 4.5)-acetonitrile (86:14,...

The resolution of mixtures of C16-C24 normal-chain fatty acids by reversed-phase partition chromatography.

Stand oils (fish drying oils) made from the body oil of the pilchard (Sardina ocelktta Jenyns) are of commercial importance in South Africa and, as part of a general study of these and other polymerized oils (cf. Joubert & Sutton, 1952), the need arose for an analytical method suitable for the separation of mixtures of saturated and unsaturated acids having from 16 to 24 carbon atoms in the cha...
