Abstract
A renewable-reagent fiber optic chemical sensor has been developed for measuring the partial pressure of carbon dioxide in ocean waters. A colorimetric pH indicator is delivered at a controlled flow rate through capillary tubing to the fiber tips. The fibers measure the color changes induced by CO2 diffusion across a gas-permeable silicone membrane. Multi- wavelength detection is used to correct for system drift. Factors affecting the sensitivity and stability of the response are discussed.
