Details
HI4001-00 is an alkaline ionic strength adjuster (ISA) solution for use with ammonia and cyanide ion selective electrodes (ISEs). Hanna ISA solutions are formulated to fix the ionic strength of a sample and standards so that they are both constant. Without addition of ISA, an ion selective electrode would measure ion activity; addition of ISA stabilizes the ionic strength and permits measurements as ion concentration. With some ISEs, the ISA solution is also used to adjust the solution’s pH or to remove any potential interferences from competing ions that are present.

Importance of ISA*
- Fixes a solution’s ion activity to be constant so concentration can be determined
- Adjusts the pH of a solution required for some ISEs
- Complexes interfering ions in a sample to allow measurement of free ions of interest
* If an ISA solution is used with a sample, then it must be used with the calibration standards in equal proportions. -
