  • Method and apparatus for the coulometric detection of dissolved gases particularly TCO.sub.2 in seawater
    Patent number: 5364594
    Abstract: A system for coulometric TCO.sub.2 analysis wherein a sample bottle is pressurized by a head space gas having a CO.sub.2 composition which approximates the dissolved CO.sub.2 concentration in the sample. The head space gas transfers to sample to a pipette. The sample is then transferred to a stripper where the sample is degassed. Two carrier gas lines flush the stripper and transfer the CO.sub.2 to a coulometer.
