BEAN

BEAN is designed to facilitate the evaluation and identification of functional buffer chemistries for ITP. Given a user-defined chemistry system, BEAN solves a set of coupled, non-linear integral conservation equations to determine whether a specific analyte is focused by the ITP system, and estimates quantities of interest in the design of related ITP processes. These quantities include zone concentrations, pH, and effective (observable) mobility values. BEAN also computes 972 variations of the specified ITP chemistry, including a broad range of buffer titrations and ion mobilities. All the calculations performed in BEAN include ionic strength and finite ionic radius effects, and the solver handles species with arbitrary valence. The tool further includes an easily searchable database of 521 commonly used electrolytes.

STEEP Buffer Calculator

A useful Matlab GUI implementation of Simulation of Temperature Effects on ElectroPhoresis calculator. STEEP evaluates pH, ionic strength, conductivity and effective mobilities of any number of weak/strong acids, bases or ampholytes. Includes temperature effects on degree of ionization, ionic strength correction and ion solvation. (Updated April 2013)

Buffer Calculator
