The present work is concerned with the development of an optical-fibre sensor for monitoring pH in the foregut in the extended range 1.0-8.0. Controlled pore glasses (CPGs), with covalently bound chromophore, are fixed at the end of plastic optical fibres using a proprietary process. A good sensitivity, fast response time, the small dimensions of the probe and the biocompatibility of the materials utilized make the sensor suitable for in vivo measurements.

Abstract
The present work is concerned with the development of an optical-fibre sensor for monitoring pH in the foregut in the extended range 1.0-8.0. Controlled pore glasses (CPGs), with covalently bound chromophore, are fixed at the end of plastic optical fibres using a proprietary process. A good sensitivity, fast response time, the small dimensions of the probe and the biocompatibility of the materials utilized make the sensor suitable for in vivo measurements.File in questo prodotto:
