Application of capsule-type packing materials for reversed-phase liquid chromatography in cosmetic analysis.

EVALUATION OF THE USE OF ANIONIC/ NONIONIC MIXED MICELLES IN REVERSED PHASE LIQUID CHROMATOGRAPHY OF CHLOROPHENOLS

The use of aqueous mixed micellar system consisting of sodium dodecyl sulfate (SDS) and polyoxyethylene (23) dodecanol (Brij-35) as the mobile phase in reversed-phase liquid chromatography was studied. A group of chlorophenols was used as the test mixture. Adding organic modifier to the system showed that the use of low concentrations of organic additives improves efficiency in SDS/Brij-35 mixe...

Noncrystalline L-Phenylalanine-Silica Hybrid Composite Materials for High Selective Reversed Phase Liquid Chromatography

Determination of monosaccharides in cider by reversed-phase liquid chromatography

A reversed-phase high-performance liquid chromatographic (HPLC) method is described for the simultaneous determination of aldoses and uronic acids in cider, previously derivatized with p-aminobenzoic ethyl ester (ABEE). Narrow-bore C8 columns are recommended as this alternative provides good separation efficiency, along with greater economy and sensitivity. Detection limits for aldoses (glucose...
