Use of solid amalgam electrodes in nucleic acid analysis

Abstrakt

Mercury meniscus modified solid amalgam electrodes of silver and of copper proved experimentally as acceptable substitutes for the hanging mercury drop electrode in highly sensitive cathodic stripping voltammetric analyses of nucleic acids and their components. Their surfaces can be simply reactivated electrochemically. The analyses are best done in weakly alkaline solutions, in case of silver amalgam electrode copper(II) ions can be added to the solution.
