Method and apparatus for determining the carbon activity of fluids
Abstract
Abstract THE CARBON ACTIVITY OF A FLUID OF UNKNOWN CARBON CONTENT IS DETERMINED BY BRINGING THE CARBON-CONTAINING FLUID INTO CONTACT WITH A HOLLOW, SEALED PROBE THE WALLS OF WHICH ARE MADE FROM A MATERIAL WHICH IS IMPERVIOUS TO THE FLUID AND IN WHICH CARBON FROM THE FLUID WILL DISSOLVE AND DIFFUSE. THE HOLLOW PROBE CONTAINS A GAS WHICH WILL REACT REVERSIBLY WITH CARBON WITH A CONCOMITANT CHANGE IN THE TOTAL NUMBER OF MOLECULES COMPRISING THE GAS PRESENT IN THE SEALED PROBE. CARBON IN THE PROBE WALL (PRESENT THEREIN AT A LEVEL REFLECTING THE CARBON ACTIVITY OF THE FLUID BEING MONITORED) REACTS REVERSIBLY WITH THE GAS WITHIN THE PROBE UNTIL EQUILIBRIUM CONDITIONS ARE ATTAINED. MEANS ARE PROVIDED FOR DETERMINING THE TOTAL NUMBER OF MOLECULES OF GAS CONTAINED IN THE SEALED PROBE WHICH, IN TURN, IS A MEASURE OF THE CARBON ACTIVITY OF THE FLUID IN CONTACT WITH THE SEALED PROBE.
