HI-4010-30 is a fluoride solution kit that contains FOUR bottles each of the following:
The standards are used to calibrate the fluoride solid state Ion Selective Electrode (ISE), while the TISAB II solution is added to samples to stabilise the ionic strength. The HI-4010-11 and HI-4010-10 standards come pre-mixed with TISAB II ionic strength adjuster, so they are ready to use for calibration without any further addition of ISA.
Samples that are measured after calibrating with the HI-4010-11 and HI-4010-10 standards need to have the appropriate volume of HI-4010-00 TISAB II added before taking any measurements with the fluoride ISE.
