Question
Is the Nitrate IntelliCAL™ ISE (ion selective electrode) suitable for use in seawater, brine, or brackish water?
Summary
The Nitrate IntelliCAL™ ISE is not compatible with seawater, brine or brackish water
Answer
No, the IntelliCAL™ ISENO3181 Nitrate Ion Selective Electrode (ISE, catalog number ISENO318101 or ISEN0318103) is not able to detect nitrate ions in saline samples. The high amount of chloride, bromide, and iodide ions interfere with this probe.
