Product Overview

• HI4010-00 is a 500 mL bottle of TISAB II solution for fluoride ion selective electrodes. Hanna ISA solutions are clearly labeled with lot number and expiration date and are hermetically sealed with a tamper-evident seal to ensure solution quality. Hanna's solution line is specially formulated and has a 5-year shelf life from the date of manufacture for unopened bottles.

• Required for fluoride measurement

• Hermetically sealed bottle with tamper-evident seal

• Clearly marked lot number and expiration date

• HI4010-00 TISAB II is an ionic strength adjustment solution for fluoride ion selective electrodes (ISEs). Hanna ISA solutions are formulated to fix the ionic strength of samples and standards so that it remains constant. Without the addition of ISA, ion selective electrodes will measure ion activity; the addition of ISA stabilizes the ionic strength and allows measurement of ion concentration. For some ion exchange systems, ISA solutions are also used to adjust the pH of the solution or eliminate any potential interference from competing ions present.

• TISAB II is used in water sample analysis to provide a constant ionic strength for samples and standards. The solution also adjusts the pH background of the solution and forms complexes with various metal ions (such as aluminum and iron) and compounds with fluoride. The complexing ability of TISAB II ensures that total fluoride can be determined.

• Importance of ISA*

• Fixes the ionic activity of the solution to a constant so that concentration can be determined

• Adjusts the pH of the solution required for some ISEs

• Complexes interfering ions in the sample to measure the free ion of interest

• *If ISA solution is used with samples, it must be used with calibration standards in equal proportions.
