Physicochemical Characterization of the Strychnos Alkaloids by Capillary Zone Electrophoresis

Physicochemical characterization of the Strychnos alkaloids by capillary zone electrophoresis.

A capillary zone electrophoresis (CZE) method has been developed for investigating the physicochemical characteristics of five Strychnos alkaloids in Strychnos nux-vomica L. Firstly, the dissociation constants of the five Strychnos alkaloids were determined, based on the relation between the effective mobility of the solutes and the buffer pH. The mathematical relationship was strictly deduced ...

awkt: A Physicochemical Parameter Estimation Tool for Capillary Zone Electrophoresis

We introduce the open source parameter estimation tool awkt. It is primarily aimed at assisting in the characterization and identification of globular proteins using capillary zone electrophoresis. The program untangles a proteins’ charge-to-size ratio by applying nonlinear least-squares optimization to a particular closed-form solution of the Nernst-Planck equation. Numerical estimates for the...

HUMIC SUBSTANCES Capillary Zone Electrophoresis

Humic substances (HS) which are widespread in the soil, present structural complexity and polyelectrolyte properties. Many techniques and methods have been used to obtain more information about them, as reviewed by Davies and Ghabbour in 1999. The characterization of HS has been the focus of intense research for many years because the organic matter in soil contributes to the quality of the soi...
