Water Hardness 4M KCl Ionic Strength Adjuster Solution

The use of The Water Hardness 4M Ionic Strength Adjuster (ISA) is necessary as an additive when using an Ion Selective Electrode (ISE) for the measurement of Water Hardness. The ISA is added to both the Ion Selective Electrode Calibration Solution (ISE) and the sample, so as to keep the ionic strength of both standard and test high, eliminate matrix effects and suppress or eliminate interfering ions. The product has guaranteed stability throughout its entire shelf life, even after opening the bottle.
- High Ionic Strength
- Aqueous Matrix
- Suppresses interfering ions, eliminates matrix, hysteresis or liquid junction potentials
- Eliminates or reduces error due to temperature co-efficient of variation between sample and calibration standard
