HI-4010-12
HI-4010-12 is a 2 ppm (mg/L) fluoride standard that is premixed with TISAB II. TISAB II is an ISA solution used to fix the activity of the fluoride ions in the solution so that a concentration measurement can be made.

The TISAB II also reduces interference from a low pH and from interfering ions, which could make fluoride undetectable by the ISE.
This solution is used to calibrate the fluoride solid state ion selective electrode (ISE).
