Chiral Separation of β-Adrenergic Blockers in Human Plasma by SPE-HPLC

0) followed by elution with methanol containing 0.1% acetic acid. Chiral-HPLC was carried out on CelluCoat (250 ? 4.6 mm, 5.0 ?m silica particle size) column using different combinations of n-heptane?ethanol?diethylamine at 1.0 and 2.

Temporal trend (1988–2008) of hexabromocyclododecane enantiomers in herring gull eggs from the german coastal region

? HBCD levels in pooled eggs archived for the German Environmental Specimen Bank. ? HBCD levels are consistent with those observed elsewhere in Northern Europe. ? HBCD contamination displays nearly exclusively ?-HBCD. ? Throughout but location-dependent enrichment of (?)-?-HBCD. ?

Enantiomer separation and indirect chromatographic absolute configuration prediction of chiral pirinixic acid derivatives: Limitations of polysaccharide-type chiral stationary phases in comparison to chiral anion-exchangers

Absolute configurations of individual enantiomers were assigned chromatographically via elution orders on the chiral anion-exchangers and were confirmed by stereoselective syntheses via Ewans auxiliaries that have lead to enantiomeric products with known absolute configurations.

Immobilization of 3,5-dimethylphenylcarbamates of cellulose and amylose onto silica gel using (3-glycidoxypropyl)triethoxysilane as linker

The 3,5-dimethylphenylcarbamates of cellulose and amylose were effectively immobilized onto plain silica gels as chiral packing materials (CPMs) for HPLC by means of intermolecular polycondensation of triethoxysilyl groups introduced with (3-glycidoxypropyl)triethoxysilane.

HPLC-method for determination of permethrin enantiomers using chiral β-cyclodextrin-based stationary phase

The liquid chromatographic separation of permethrin enantiomers on chiral ?-cyclodextrin-based stationary phase has been investigated. All four enantiomers are obtained by using simple methanol and water mobile phase, under gradient mode. The method was optimized and validated.
