The fabrication and sensor properties of polyaniline-platinum oxide chemoresistors in the presence of combustible gases such as hydrogen, methane, ethylene, acetylene and carbon monoxide is reported. Prior conditioning of the sensors in a hydrogen atmosphere resulted in increased selectivity and sensitivity for hydrogen in air at concentrations between 1000 and 5400 ppm. The conditioned sensors showed negligible response to hydrocarbons and carbon monoxide.

“…Since the type I thin-layer cell seemed to provide the most flexible design, it was chosen for more detailed studies, including optimization of the design parameters. Practical applications employing this cell have been published [13][14][15]. Initial evaluation of the PEC flow cells was carried out using potassium ferrioxalate (actinometer) and Nnitrosodiethylamine (NDEA).…”

Several photoelectrochemical flow cells have been designed and their analytical performances evaluated and compared. Two cell geometries, thin-layer and wall-jet, and three irradiation configurations differing in the relative position of the irradiation and detection points have been considered. In the first configuration ("adjacent"). the irradiation point is located upstream of the working electrode. In the second arrangement ("above"), the light irradiates the solution above the working electrode as %-ell as the electrode surface. The third configuration ("on") involves the use of an optically transparent electrode through which the light passes before irradiating the solution present on the electrode surface. The "adjacent" thin-layer cell was found to be the most practical and useful design. The photoelectrochemical efficienq of this cell was optimized and evaluated in terms of window and channel size.

“…In the 1990s, conducting polymer-based chemical sensors and biosensors were mostly based on electrochemical signal transduction [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. Today, electrochemical sensors continue to dominate , although optical signal transduction has gained more interest in recent years [32,36,40,42,51,55,61,62].…”
