Ion selective electrode calibration curve
WebThe Ion-Selective Electrodes are part of a group of relatively simple and inexpensive analytical tools which are commonly referred to as sensors. The pH electrode is the most well-known and simplest member of this group and can be used to illustrate the basic principles of ISEs. The Fluoride ISE is intended for measuring fluoride concentrations … WebS is the slope of the calibration curve and equals β(0.05916); C is the analyte ion (F-) concentration. This equation can be rearranged to give The analyte ion concentration after any addition of the standard is given by where C0 is the analyte concentration before any standard is added; V0 is the volume of the solution before any standard is ...
