Several variables that can affect reproducibility of both the peak height and the migration time in capillary electrophoresis (CE) were investigated here. A great part of the imprecision in CE for migration time is related to the interaction of the analyte with the capillary wall. Within a run, acidic compounds with long migration times have a higher relative standard deviation. In general, conditions that decreased the migration time, such as a short capillary length, tended to enhance the… CONTINUE READING
