Analysis of epinephrine from fifteen different dental anesthetic formulations by capillary electrophoresis

A robust method for the quantification of epinephrine from 15 different commercial dental anesthetic formulations is developed using CE. This work presents an extension to a method reported earlier. The solvability of several anesthetic compounds was improved through appropriate dilutions and the addition of sodium dodecyl sulfate to the separation background electrolyte. By controlling the mobility of the analyte at different pH values, a …
