-320-A REAL TIME DETECTION OF INTRAMYOCARDIAL pH CHANGE USING ANTIMONY NEEDLE pH SENSOR

Fabrication of a needle-type pH sensor by selective electrodeposition

This manuscript reports on the development of a needle-type sensor for in situ on-site measurement of pH. Conventional pH microelectrode sensors are fabricated by pulling glass pipettes and applying ion-selective films at the tip. However, these sensors suffer from low fabrication yields and short sensor lifetime due to disruption or loss of the ion-selective membrane after repeated use. The de...

Detection of Fuel Adulteration in Real Time Using Optical Fiber Sensor and Peripheral Interface Controller

Detection of fuel adulteration in real time is the most important need of the world as it generates the hazardous effects on the environment, living and nonliving things. Various automotive users and fuel providers may mix kerosene in petrol and diesel. Adulterated fuel increases air pollution, as well as reduces the performance of vehicle engines. Such a malpractice in fuel is prevailing becau...

Optical 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...

Detection of Congenital Mullerian Anomalies Using Real-Time 3D Sonography

Comparison of pH Data Measured with a pH Sensor Array Using Different Data Fusion Methods

This paper introduces different data fusion methods which are used for an electrochemical measurement using a sensor array. In this study, we used ruthenium dioxide sensing membrane pH electrodes to form a sensor array. The sensor array was used for detecting the pH values of grape wine, generic cola drink and bottled base water. The measured pH data were used for data fusion methods to increas...
