The application relates to an ellipsoidal single capillary lens cutting region selection method, which comprises the following steps: collecting profile data of an ellipsoidal single capillary to be cut; selecting a plurality of lens interested cutting regions according to the profile data and preset cutting data, and constructing a profile equation for each interested cutting region; solving the surface shape error of each interested cutting region based on the profile equation by using an improved cosine crow search algorithm, and updating the individual position according to Levy flight during calculation; until the surface shape errors of all the interested cutting regions are calculated, the minimum surface shape error value and the corresponding interested cutting region are output as the best cutting region. When the individual position is updated, the Levy flight is used to replace the fixed step length, the blindness of the cosine crow search algorithm is reduced, the problems that the traditional capillary cutting is prone to falling into local optimization and the convergence speed is slow are solved, and the calculation of the single capillary surface shape error is more efficient and stable.

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.
