Area of Science:

  • Analytical Chemistry
  • Physical Chemistry

Background:

  • Capillary Zone Electrophoresis (CZE) is a powerful separation technique.
  • Mathematical modeling aids in understanding complex electrophoretic phenomena.
  • Accurate prediction of CZE parameters is crucial for method development.

Purpose of the Study:

  • To introduce PeakMaster, a computer implementation of a CZE mathematical model.
  • To enable calculation of system eigenzones and analyte parameters.
  • To facilitate the assessment of indirect detection, conductivity detection, and peak broadening.

Main Methods:

  • Implementation of a mathematical model for CZE.
  • Calculation of eigenmobilities, background electrolyte (BGE) parameters, and analyte properties.
  • Simulation of electropherograms based on input BGE composition, analytes, and instrumental configuration.

Main Results:

  • The model calculates key parameters like eigenmobilities, BGE properties (pH, conductivity, buffer capacity, ionic strength), and analyte characteristics (effective mobility, transfer ratio, molar conductivity detection response, relative velocity slope).
  • PeakMaster allows for the assessment of indirect and conductivity detection, as well as peak broadening due to electromigration dispersion.
  • Simulated electropherograms are generated in a user-friendly manner and are comparable to experimental results.

Conclusions:

  • PeakMaster provides a valuable tool for understanding and predicting CZE behavior.
  • The model successfully aids in the inspection of BGEs, even without a stationary injection zone.
  • This computational approach enhances CZE method development and optimization.
