Abstract The Orion Divalent Cation Specific Ion Electrode No. 93-32 was evaluated for suitability in monitoring or in-situ marine applications as a magnesium ion sensor. The electrode was tested with three separate modules for the following parameters: accuracy, precision, temperature dependence, short- and long-term stability, durability, sensitivity to variations in light intensity and flow conditions, response time as a function of temperature and concentration, and variability between modules. The sensor, a 'liquid ion-exchange' type, was evaluated at 10C and 25C in freshwater, synthetic seawater (35-, 20- and 5-ppt salinity), and natural waters (IAPSO Standard Seawater, Atlantic Ocean Water and Chesapeake Bay Water). A description of sensor, theory of operation, and a summary of the test results are included.
Notes "March 1979." Includes bibliographical references (page 14). "Interagency agreement no. D5-E693, project no. EAP-78-BEA, program element no. 1 NE 625C."
