Determination of NO3- ions with a selective electrode (potentiometry)
Use of the electrode
There is no prefilling, unlike the calcium ion selective electrode. Both parts A and B are usually sealed.
During use: Avoid contact with organic solvents (chlorinated solvents, aldehydes, ketones, and carboxylic acids) so as not to impair the integrity of the PVC membrane.
At the end of use, the electrode is rinsed with distilled water and stored dry.
