Abstract

A modular fiberoptic sensorial instrument for (bio-)chemical analyses will be presented. The sensing mechanism is based on Capillary Optical Fiber (COF). A measurand of liquids or gaseous form present in the COF cavity influences the chemical transducer covering the inner wall of fiber, and by this way changes the intensity of guided radiation. The wavelength scanning through the characteristic region enables the identification and quantitative analysis of the measurand. Every COF modulus is sesibilized for specific chemicals. The application of new immobilized chemical transducer and theoretical description of the sensing effects will be presented, too.
