Electrochemical precipitation of neptunium with a micro electrochemical quartz crystal microbalance. [PDF]

J Radioanal Nucl Chem, 2020
Microliter volumes are used in electrochemical detection and preconcentration of radionuclides to reduce the dose received by researchers and equipment. Unfortunately, there is a lack of analysis of radionuclides with coupled electrochemical techniques and microliter volume reactors.

A new electrochemical cell adapted to quartz crystal microbalance measurements

Electrochemistry Communications, 2000
As the resonance frequency of an oscillating quartz changes upon the deposition of a given mass to the crystal surface, it can be used as a very sensitive mass measuring device. Despite a growing interest in the use of electrochemical quartz crystal microbalance (EQCM), there is still no commercial available measurement cell which can satisfy all the ...
