Generally, there are three main electrode or sensor problems when performing a non-aqueous titration. The first is the problem of having an aqueous electrolyte with a non-aqueous solvent. Replacing the electrolyte in the electrode easily solves this. The second problem relates to the fact that the sample is non-conductive, resulting in a poor electrical circuit between measuring and reference half-cells or parts of the electrode if combined. This results in a noisy signal, particularly when using a sensor with a standard ceramic junction in the reference. A partial solution to this problem is to use a sensor with a sleeved junction, such as the DGi113 sensor. This sensor has LiCl in ethanol as the standard electrolyte and, rather than a ceramic junction, has a polymer sleeve resulting in a larger contact area between working and reference parts and therefore lower noise. The third problem is not a problem of the electrode itself, but rather the handling of the sensor. In order for a glass (pH) sensor to function correctly, it is necessary that the glass membrane (bulb of electrode) is hydrated. This is achieved by conditioning the electrode in deionized water. During the non-aqueous titration this membrane is gradually dehydrated reducing the response of the electrode. To prevent this or rectify this problem the electrode should be regularly reconditioned by soaking in water.
