✦ Synopsis
A multiple-mduzator fiber-optic sensor was employed to detect low level CO, changes m sea water pK, values of these mdlcator systems at high lomc strength were determmed, and the buzarbonate concentrations were added as calculated by the Henderson-Hasselbach equation The 7-hydroxycoumarm-4-acetic acid (HCA)-meta-Cresol Purple (MCP) mdlcator system provides a resolution of 7 pg ml -' CO, m the 200-800 pg ml-' CO, range, the CO, range of sea water
