More Information
Summary:A method is provided for manufacturing a fiber optic sensor for detecting or measuring the concentration of carbon dioxide in a sample fluid. The method involves preparation of a suitable indicator composition (16) and incorporation thereof in a silicone capsule (14) slidably arranged over the tip of a fiber optic (12), sealed with a suitable adhesive means (18). To amplify the signal obtained, the capsule (14) is preferably fabricated so as to contain reflective particules, and tapers to a narrow tip. Novel optical sensors are also provided, as are methods for using the sensors to evaluate CO2 concentration in a sample fluid.
