Electrochemical Investigation of Amperometric Ammonia Gas Sensors

Berichte der Bunsengesellschaft für physikalische Chemie, 1990
AbstractResults of potentiodynamic and potentiostatic measurements of the electrooxidation of ammonia traces with platinum as a catalyst in a strong alkaline electrolyte are reported. To improve the performance of a fuel cell, such as an electrochemical gas sensor for ammonia traces, the hydrophobicity of the Teflon‐bonded platinum black gas diffusion ...

Electrochemical gas sensor using peo electrolyte

Solid State Ionics, 1990
Abstract A new galvanic sensor for monitoring nitrogen dioxide was developed by using a poly (ethylene oxide) complex of silver trifluoromethane sulphonate electrolyte. The sensor, which is expressed as Au/P(EO) 4.5 AgCF 3 SO 3 /Ag, is a small disk (id, 13 mm). The thickness of gold, film and silver are 25 nm, 30 μm and 1 mm, respectively.

Potentiostat solution for electrochemical amperometric gas sensor

2012 35th International Spring Seminar on Electronics Technology, 2012
This study deals with intrinsic parameters of electrochemical amperometric gas sensors with a solid-state polymeric electrolyte. An experimental electrochemical NO 2 sensor based on organic ionic liquid was developed. Subsequently, electrical and mechanical parameters of the sensor were studied and an appropriate potentiostat circuit was designed for ...

Integrated electrochemical transistor as a fast recoverable gas sensor

Analytica Chimica Acta, 2011
A new design of conductometric chemical sensors based on conducting polymers as chemosensitive elements was suggested. The sensor includes six electrodes. Four inner electrodes coated by chemosensitive polymer are used for simultaneous two- and four-point resistance measurements thus providing information on the bulk polymer resistance and on the ...

Pulsed Potential Amperometric Electrochemical Gas Sensors

ECS Meeting Abstracts, 2018
Pulsed electrochemical techniques are well known and are well reviewed. The various discussions and derivations of the theory of pulsed voltammetry or polarography extant make clear the motivations behind the development of these techniques: increasing the analytical sensitivity of these methods by separating, in time, the charging current and the ...

Rapid dissolved gas analysis by means of electrochemical gas sensors

Proceedings of 2002 IEEE 14th International Conference on Dielectric Liquids. ICDL 2002 (Cat. No.02CH37319), 2003
Rapid, introductory analysis of gases dissolved in insulating oil (DGA) carried out in the field can help in effective screening of faulty transformers as well as minimising number of classical laboratory chromatographic DGA tests. It is also crucial for shortening a time gap between oil sampling and its analysis.
