The Microcell HC measuring system is perfectly suited for the electrochemical characterization of low to highly-viscous liquids, gel-like and polymeric as well as solid samples and of heterogeneous systems. Depending on the measuring cell, the experiments can be carried out either in a two- or three-electrode configuration. In all cases, only a very small sample amount is needed (several measuring cells only need an amount of a few milligram). Hence, even substances which are only available in small amounts or are expensive can be characterized.
In contrast to the Microcell HC Closed and Open systems, the Microcell Passive does not have temperature control built in. It is instead designed to be used e.g. in an oven. Using external temperature regulation reduces complexity and expense, but at the cost of less accurate temperature control due to e.g. temperature gradients in the oven.
Many studies have been carried out using the Microcell HC system and several articles reporting the obtained results have been published in international peer-review journals. Established fields of research are for instance
- The determination of the temperature-dependent dc-ion conductivity of...
- ionic liquids
- battery electrolytes
- polymer-electrolytes
- The structure and dynamics of the electrochemical interface of ionic liquids and solid electrodes
- Li-ion battery (half and full cells) performance under temperature control
- Characterization of active materials for suprtcapacitors
- The investigation of HOMO-LUMO gaps of dyes dissolved in organic solvents
- Spectro-electrochemical studies of optically active redox pairs
The Microcell HC system supports almost all electrochemical techniques, like for example
- Electrochemical Impedance Spectroscopy
- Cyclic Voltammetry
- Potentiostatic/galvanostatic charge/discharge cycling
- Spectroelectrochemistry
- In-situ electrochemical raman spectroscopy
- Electrochemical quartz microbalance measurements
- Van-der-Pauw surface resistance measurements
