Chemiluminometric determination of propranolol in an automated multicommutated flow system

The calibration graph was linear over the range 20-150 mg l−1 of propranolol hydrochloride with a relative standard deviation lower than 1.6% (n = 7). The results were in agreement with those obtained by the reference procedure with a relative deviation between −3.8 and 3.7% and a sampling rate of about 27 samples h−1.
