摘要： An electrochemical polymerization based salt content analyzer configured to determine salt composition in a direct, fast, and serial manner. The salt content analyzer includes three electrodes: a working electrode, a counter electrode and a reference electrode. In operation, the current passing through the electrodes as a sweeping voltage is applied may be analyzed to determine the salt content of the analyte. The working electrode includes an access control mechanism to only expose a fraction of the working length of the working electrode to the outside environment at any given time. The access control mechanism is advanced between tests to expose a fresh portion of the working electrode. Thus, testing may be performed in a serial manner.

摘要： A sensing element, for use in determining the presence and/or concentration of a species in a solution, comprises a flat insulating substrate (10) having at least one thin metallic electrode (16) deposited on it and overlaid with an insulating layer (20). The electrode (16) and insulating layer (20) bridge a weakening groove (12) formed in the substrate. Immediately before use, the element is broken along the groove to expose a cross-sectional surface (24) of the element, and thus a cross-sectional working surface (26) of the electrode. The thickness (T) of the element is comparable to or less than the concentration boundary layer thickness of the solution. This exposed working surface is the only part of the electrode in contact with the solution. In use, the element can be vibrated so as to improve its sensitivity.

摘要： A method of preconditioning an electrode for use in a plating bath monitoring process. The method involves applying at least one anodic signal to an electrode in contact with the plating bath solution in order to yield a reproducibly clean and stabilized electrode surface, and then applying a plating signal to deposit a layer of metal on the anodically treated electrode. The resultant preconditioned electrode improves the accuracy and precision of subsequent voltammetric monitoring measurements for a variety of different plating baths. The method is easily integrated with and thereby enhances the capabilities of known voltammetric plating bath monitoring processes.

摘要： One of the fundamental limitations of voltammetric detectors in flow analysis is the problem of passivation or contamination of the working electrode. The present invention proposes a voltammetric detector based on the wall-jet principle which incorporates the concept of a replaceable working electrode. The voltammetric detector represents a significant improvement over existing detectors which are fully enclosed or sealed devices precluding easy replacement of the working electrode.The design of the present invention provides a detector where the top is fully open and where the solution volume is maintained by the outlet positioning. The other feature of the proposed detector is an optimised geometry that provides well defined wall-jet flow characteristics which is not provided in existing detectors.

摘要： A streaming current detector which utilizes the test flow stream to keep the electrodes of the detector probe washed and its dielectric surfaces from becoming fouled. The test stream first enters a housing surrounding the probe at a position proximate the inlet to a transverse passageway within the probe. Most of the flow moves directly through the probe along the transverse passageway, but a small portion of this flow is sucked into capillary-sized channels within the probe by the action of a piston during its upstroke and then expelled from them back into the transverse passageway during the downstroke. The flow leaving the transverse passage plummets downwardly where it joins a smaller fraction of the test stream that did not enter the transverse passageway and together they are discharged out the bottom of the housing. There are no low velocity or stagnate areas where solids can accumulate either in the housing surrounding the probe or within the probe itself. The flow velocity is kept high everywhere so that floc which does come in contact with the probe is constantly washed off from the flow stream. In this manner, the inlet to the probe, its through passageway and its capillary-sized channels as well as the housing surrounding the probe are kept free from contamination allowing both a continuous operation and a higher electrical output. The higher electrical output makes possible a signal with remote sensing capabilities. This design answers the long standing problem of keeping a streaming current detector clean during operation.
