Force and mechanical measuring equipment
– ISISA solution helps stabilize ions in samples and standard solutions.
– Used for ion selective electrode to measure fluoride.
– Very necessary when measuring Fluoride.
HI4013-06 is a nitrate-resistant ISA solution for use with nitrate ion selective electrodes (ISE). When using ISE nitrate To measure nitrate in samples such as drinking water and wastewater, HI4013-06 solution must be added to stabilize the ionic strength of the solution, as well as to remove interfering ions, including chloride.
Hanna ISA solutions are prepared to fix the ionic strength of the sample and standards so that both remain constant. Without additional ISA, an ion-selective electrode measures ion activity; ISA addition stabilizes ionic strength and allows measurement of ion concentration. With some ISEs, ISA solution is also used to adjust the pH of the solution or to eliminate any potential interference from competing ions present.
