Abstract | I have developed an analytical method for the determination of molecular hydrogen in seawater. It is based on the change of hydrogen concentration in a 30 cc. volume of air as it is equilibrated with a one-liter sample of seawater. The change in hydrogen concentration in the air is measured using a gas chromatograph with a helium ionization detector. The system has been utilized aboard ship on several occasions and has been proven to be both dependable and readily transportable. The accuracy of a single measurement is limited to about plus or minus fifteen per cent by the analytical precision of the method. The precision is limited by the random errors in the GC analysis. Shipboard and laboratory experiments have shown that contamination of near-surface and near-bottom samples can be a major problem unless special precautions are taken. |
