Transient modelling of capillary electrophoresis

Dynamic computer simulations of electrophoresis: A versatile research and teaching tool

“…Execution time, which can vary between a few seconds and a full month, depends on the numerical scheme [57,63,65,66,68,69,138], on the PC's chip (Fig. 1A), the PC's operational configuration (Fig.…”

“…Selection of the appropriate simulation parameters, such as the number of segments and the applied power level, is crucial for success [3,4,57,63,66,68]. The widths of boundaries with a steady-state shape are dependent on the applied power level, i.e.…”

“…behavior not expected to occur in an experiment, the simulation should be repeated without invoking smoothing, and the results compared with the suspect data. Instead of an increased mesh, as with the integration schemes employed in GENTRANS, SIMUL5 and the 2-D model, other algorithms have been tested in various laboratories [57,63,65,66,68,69,138]. Several of the proposed procedures, however, were found to provide data with undesired boundary distortions [57,63,65] and are therefore no longer in use.…”

Recently described approaches [68,69,138], however, might pave the way for high-resolution simulations at high current densities that can be performed without peak distortions and with lower computation times.…”

“…2D, 8 and 9. In this example, which has been used as benchmark for ITP to characterize the performance of various simulators [63,66,68,69], the sample comprising pyridine and aniline (10 mM each) and 20 mM acetic acid (pH 4.87) was applied between the leader (18 mM NaOH and 20 mM acetic acid, pH 5.71) and terminator (40 mM balanine and 50 mM acetic acid, pH 4.12) and initially occupied the space between 1 and 2 cm of the 12 cm column (Fig. 8A).…”
