PLATINUM ANODES AND CATHODES
For best results, we recommend the use of the anodes and cathodes listed here.
The paddle form anode is recommended where considerable agitation is required.
The loop anode is made of No. 16 platinum iridium wire insuring the rigidity required for successful rotation at high speed.
When making copper and lead determinations simultaneously, the gauze anode is recommended, as it offers a larger surface for deposition.
The cathode is made of 52-mesh wire gauze 1 3/8 inches diameter. Cathodes of smaller diameter are impractical. The gauze cathode has been found superior to the perforated type as it allows freer circulation.
