A new method for benzocaine determination employing FIA and HPLC with electrochemical detection on a carbon paste electrode was developed. The optimum conditions for the determination were found. Carrier solution for FIA consisted of B-R buffer pH 4 (80 % methanol, v/v) and used flow rate was 1.0 mL min À1. Mobile phase for HPLC consisted of B-R buffer pH 4 (75 % methanol, v/v) with flow rate 0.4 mL min À1 . Working potential of + 1.2 V was employed. Practical applicability of the methods was tested on the determination of benzocaine in selected pharmaceuticals. The results were in agreement with results obtained using spectrophotometric detection and with one exception also with the content declared by the manufacturer.
