Abstract

This paper designs an undersea in-situ anion analyzer that could work in the depth of 4000 meters. Based on the method of ion chromatography, the device detects the concentrations of F^-, Cl^-, Br^-, NO₃^-, SO₄^2-, PO₄^3- etc. The analyzer consists of there major parts: a pressure housing containing the control unit, an oil-filled housing containing the fluid analysis part and a peristaltic pump for transferring seawater and elution, and it has functions of in-situ calibration and seawater dilution. The system performed successfully in a serious of experiments.
