The application of capillary electrophoresis to the analysis of vitamins in food and beverages

Autor: V C, Trenerry

Publikováno v: Electrophoresis. 22(8)

Capillary electrophoretic (CE) methods have been used to separate and determine a wide range of water-soluble vitamins in pharmaceutical preparations, but has found limited application in determining vitamins at naturally occurring levels in food and

Method optimization: determination of histamine in fish by capillary zone electrophoresis

Autor: V C, Trenerry, P A, Marshall, K, Windahl

Publikováno v: Journal of capillary electrophoresis. 5(1-2)

Capillary zone electrophoretic (CZE) methods are gradually gaining acceptance for quantitative analyses in testing laboratories. However, some procedures are often instrument and operator dependent. Modifications to a published procedure for the rout

The separation and determination of quinine in bitter drinks by micellar electrokinetic capillary chromatography

Autor: V C, Trenerry, C M, Ward

Publikováno v: Journal of capillary electrophoresis. 3(5)

A rapid method for the determination of quinine in bitter drinks by micellar electrokinetic capillary chromatography (MECC) with ultraviolet (UV) detection is described. The beverage is simply diluted with deionized water, filtered, and analyzed usin

The direct separation of the diastereoisomers and enantiomers of the fungicide triadimenol by micellar electrokinetic capillary chromatography

Autor: B D, Williams, V C, Trenerry

Publikováno v: Journal of capillary electrophoresis. 3(4)

The direct chiral separation of the four enantiomers of the systemic fungicide triadimenol has been investigated using micellar electrokinetic capillary chromatography (MECC) with cyclodextrin (CD) chiral selectors and organic modifiers. The capillar

Synthesis of bicyclobutanes: exclusive insertion of a cyclopropylidene into primary rather than tertiary carbon-hydrogen bonds

Autor: V. C. Trenerry, David P. G. Hamon

Publikováno v: Tetrahedron Letters. 15:1371-1374

Das Dibromcyclopropan (I) erhalt man aus 2,3,4-Trimethyl-penten-(2) und Bromoform/Kalium-tert-butylat in Pentan, es liefert bei der Behandlung mit Methyllithium bei -40°C, 10°C oder 36°C die Bicyclobutane (II)-(IV).
