PDF-(BOOK)-Pulsed Electrochemical Detection in High-Performance Liquid Chromatography (Techniques

Diese Originalarbeit bietet eine detaillierte Beschreibung elektrochemischer Pulsdetektionsmethoden wie der gepulsten Voltammetrie oder der gepulsten Amperometrie Die Kopplung solcher Nachweissysteme an ein Stofftrennungssystem HPLC erlaubt die Erfassung biologisch aktiver Verbindungen wie Kohlenhydrate Peptide und Amine in komplex zusammengesetzten Gemischen Vor und Nachteile der Methoden werden ebenso diskutiert wie die instrumentelle Ausrstung und Mglichkeiten der Fehlersuche 1197.

Descending paper chromatography is an analytical technique in which the mobile phase moves downward through the stationary phase. In other words, in this method, the development of the paper occurs due to the movement of the solvent downwards on the paper. Therefore, the solvent reservoir should be at the top of the paper. In this process, the movement of the solvent is governed by gravity as well as capillary action..

It is based on the principle of the partition of the solute between two phases/solvents.
