Abstract
The main object of this disclosure is to enable real-time impedimetric detection which provides greater sensitivity to scale formation in stainless steel tubes, as minimal changes on the capillary surface are detected in the form of an increase in the overall impedance of the system for systems in flow with real-time detection. Thus, the apparatus of the present disclosure includes at least one potentiostat, at least one working electrode (WE), at least one reference electrode (RE) and at least one counter electrode (CE), and at least one tube with an opening adapted to pass a fluid flow and at least two polymeric connectors at the ends, in which the working electrode is connected to the inlet of said tube.
