In-situ flow probe for improving the performance of electrochemical stripping analysis

Submersible flow probes, originally developed for in-situ electrochemical monitoring of trace metal contaminants, are used for minimizing common problems in stripping analysis, such as overlapping signals, intermetallic effects or ohmic distortions. These problems are alleviated via an internal delivery of an appropriate solution, containing a masking ligand, a third element, or a conductive matrix. Such attention to common problems, via in-situ manipulations of the collected metal, holds great promise for environmental and industrial applications. The coupling of fluid manipulations with the stripping sensor represents the first step towards the construction of miniaturised stripping analysers on a cable.
