Abstract : Gas chromatography was used for the routine determination of dissolved O and N in sea water. Previously, dissolved O was determined aboard ship by the standard Winkler chemical method, but dissolved N analyses were seldom made, since the manometric techniques employed were extremely difficult to carry out because of the motion of the ship. To obtain dissolved N data thus required that hundreds of samples of sea water be stored in tightly stoppered containers until the analyses could be carried out at a shorebased laboratory. The feasibility of the gas chromatographic method has been established for routine shipboard determination of dissolved gases in sea water. The method is less time consuming, sample size is reduced, no loss is experienced in either precision or sensitivity, and the instrumentation is relatively simple. In addition, the method is largely automatic and the recorded results can be analyzed at some later and more convenient time. (Author)
