Hanna ISA solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution. Hanna’s line of solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened bottle.
HI4010-05 TISAB II is an ionic strength adjuster solution for use with fluoride 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.
TISAB II is formulated for water sample analysis to provide samples and standards alike with a constant ionic strength. The solution also adjusts the pH background of the solution and complexes with various metal ions, such as aluminum and iron, that form compounds with fluoride. The complexing ability of TISAB II ensures a total fluoride measurement can be determined.
