In situ osmotic analyzer for the year-long continuous determination of Fe in hydrothermal systems In situ osmotic analyzer for the year-long continuous determination of Fe in hydrothermal systems
A submersible osmotically pumped analyzer (Fe-OsmoAnalyzer) has been adapted for the long-term continuous high resolution monitoring of iron(II) and (III) in deep-sea hydrothermal vents. Ferrozine is used as the colorimetric reagent. The detection limit for our analyzer is 0.1??M for a 0.7cm pathlength with a linear response up to 50??M. The Fe-OsmoAnalyzer uses periodic injections of...
