Metrohm Titrodes and MicroTitrodes combine two measuring electrodes into a unique metal/glass combination electrode
Depending on the titration, one would work as the indicator electrode the other as the reference.
Which, says Metrohm, means:.
No typical electrode problems.
No reference filling solution needed - no question of which electrolyte to use and no electrolyte solution precipitation.
No reference diaphragm - eliminates blocked diaphragm problems or frozen ground-glass joints.
No storage problems - simply store in distilled water. Typical applications for Titrodes:.
Acid/base titrations, aqueous or non-aqueous - the glass electrode of either the Pt or Ag Titrode is the measuring electrode.
Acidic precipitation/argentometry titrations, the Silver Titrode and Micro Titrode uses the silver ring as the indicator with the glass offering a constant reference.
In the alkaline sulphide and mercaptan titrations, Metrohm says that, again, the silver Titrodes provide consistent results with the unique combination. Other typical redox titrations such as the acidic iron (II) sulphate with KMnO4 or diazotisation with sodium nitrite, can be done very well with the platinum Titrode and the MicroTitrode
