A System for the Analysis of Dissolved Oxygen, Nitrogen and Argon in Natural Waters

摘要

A complete system has been developed for the shipboard analysis of dissolved oxygen, argon and nitrogen. The system includes an in situ sampler, chromatographic analysis for oxygen, argon and nitrogen and three modes of calibration. The system has been tested in the laboratory and at sea. Estimations of the composition of argon, oxygen and nitrogen in dry air and in air-saturated water are reported. Sea trials indicated that thermistor detectors should be used in the chromatograph instead of hot-filament detectors. (Author)
