 | Description Calcium ISA, 125mL
Features 
|
Details:
Calcium ISA ensures that all samples and standards have similar ionic strengths, which is important when using ISE electrodes.
It is important to add ISA to all standards and samples when using ISE WQSensors. By bringing the ionic strength of all samples and standards to a similar level, the effect of variable ionic strengths on the activity, and hence measured concentration, is overcome.
