Theoretical study of permselective layers on amperometric electrodes in flowing streams

Analytical Chemistry, 1991
A model consisting of the response of a porous permselective coating on an electrode in an amperometric configuration is solved for two types of concentration profile Impinging on the polymer solution Interface. A Gaussian concentration profile and a Poisson concentration profile are examined, since both profiles typically arise in both flow injection ...

Synthesis of electrodes for relativistic electron streams

International Journal of Infrared and Millimeter Waves, 1995
The condition for geometrical similarity of trajectories given by Dryden has been modified to be relativistically correct, thus allowing the complete Dryden-Harker procedure to be used to design electrodes for relativistic electron streams of limited velocity spread.

The streaming potential electrode. A senior undergraduate electrochemistry experiment

Journal of Chemical Education, 1974
Besides suggesting an upper level experiment, this article gives a mathematical treatment that should encourage a student to review the thermodynamics of electrical double layer as well as the Stockholm sign convention.

Amperometric Determination of Hydralazine Hydrochloride in a Flowing Stream at the Glassy Carbon Electrode

Journal of Pharmaceutical Sciences, 1984
A flow-injection method for the determination of hydralazine hydrochloride based on electrochemical oxidation at the glassy carbon electrode is presented. The amperometric method is highly specific and may be used to determine hydralazine hydrochloride in the presence of other drugs commonly found in its pharmaceutical dosage forms or administered ...

Streaming maxima in the iodine electroreduction at Hg electrodes in DMSO solutions

Journal of Electroanalytical Chemistry, 1979
Abstract A current maximum was observed by d.c. polarography during the electroreduction of iodine at Hg electrodes in DMSO solutions. i−t curves during the drop life were performed to characterize the observed maxima. Changes in the cation of the supporting electrolyte do not. appreciably affect the results.

Modified electrodes for electrochemical detection in flowing streams

Analytica Chimica Acta, 1990
Abstract Chemically modified electrodes exhibit unique behavior which can greatly benefit electrochemical detection in flowing streams. A review of the development and applications of modified electrodes in flow analysis is presented. Detailed discussions are given for different surface-modification strategies employed in flow analysis.

Amperometric Determination of Isoniazid in a flowing Stream at the Glassy Carbon Electrode

Analytical Letters, 1983
Abstract A flow-injection method for the determination of isoniazid based on electrochemical oxidation at the glassy carbon electrode is presented. The amperometric method is highly specific and may be used to determine isoniazid in the presence of most other drugs and/or preservatives commonly found in its pharamaceutical dosage forms or administered ...

Electrochemical response at microarray electrodes in flowing streams and determination of catecholamines

Analytical Chemistry, 1990
Electrochemical characterization of two microarray electrodes, an interdigitated microarray electrode (IDAE) and a single potential microarray electrode (SAE), was investigated in flowing streams. Amperometric responses at these electrodes were in good agreement with those of theoretical prediction. Compared to a dual-series rectangular electrode (DRE)
