Webconcentration from the calibration curve. 7.8 When analyses have been completed, rinse the electrodes thoroughl y and store them in a 1.0 mg/L sulf ide standard solution. If the electrodes will not be used more than one day, drain the reference electrode internal filling solutions, rinse with reagent water, and store dry. 8.0 QUALITY CONTROL WebFig.2 Typical calibration curve of an ion-selective electrode. Ions, present in the sample, for which the membrane is non-permeable (i.e. non-selective), will have no effect on the mesured potential difference. However, a membrane truly selective for a single type of an ion and completely non-selective for other ions does not exist.
