Atropinium scopolaminum integrated microconduits in a potentiometric analytical system.
The preparation of the flow-through tubular atropinium and scopolaminum electrodes and assemblage of the integrated microconduit potentiometric analytical system with tubular ISEs, microvalve, chemfold, electrostatic and pulse inhibitors are described. Electrochemical characteristics of new atropinium scopolaminum integrated microconduit FIA-ISEs were studied. The contents of atropine and scopolamine in drugs could be determined at almost equilibrium state at sampling rates of 120/hr. The standard deviation over the linear range was about 0.1 mV (N = 11).
