Performance of miniaturised thick-film solid state pH sensors
The performance of novel solid state Thick-Film pH sensors for water quality sampling that are designed for deployment in remote catchment areas is described. These miniaturised screen printed planar pH sensors are an alternative to conventional glass pH electrodes that have many disadvantages such as high-cost, large size, mechanical fragility and limited shape. The approach adopted here for i...
متن کاملOptical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
متن کاملNANOSTRUCTURED Fe2O3 THICK FILM AS AN ETHANOL SENSOR
Thick films of AR Grade nano Fe2O3 material with n-type semiconducting properties were prepared and tested for their gas sensing performances. Thick films of the materials were prepared by screen printing technique. The gas sensing performance was studied using static gas sensing system. The material was tested for various gases such as CO, CO2, NH3, Cl2, H2, LPG, ethanol and H2S. The nano Fe2O...
متن کاملCO2 Selective Potentiometric Sensor in Thick-film Technology
A potentiometric sensor device based on screen-printed Nasicon films was investigated. In order to transfer the promising sensor concept of an open sodium titanate reference to thick film technology, "sodium-rich" and "sodium-poor" formulations were compared. While the "sodium-rich" composition was found to react with the ion conducting Nasicon during thermal treatment, the "sodium-poor" refere...
متن کاملTiO2 thin film gas sensor for monitoring ammonia
Systematic development and mechanistic studies of sensing materials are critical to the design of higher performance gas sensing elements and arrays. Polycrystalline metal-oxide semiconductors such as SnO2 and TiO2 are among the most widely used materials for thin film-based conductometric gas sensors. The mechanistic steps responsible for the gas-induced conductance changes of polycrystalline ...
