Horiba Ionic Strength Adjustors - ISA & TISAB Item:500-CA-ISA - Calcium Ionic Strength Adjustor, 500 mL - 3200697178 300-4C-C — conductivity cartridgeIonic strength adjustors for HORIBA ion selective electrode measurements. An ISA or TISAB in the case of fluoride is added in a fixed proportion to both your standards and your samples so that every solution the electrode sees has the same background ionic strength. Why this reagent is not optional An ion selective electrode does not respond to concentration. It responds to ion activity, which is concentration multiplied by an activity coefficient
