Electrolytic preconcentration in instrumental analysis
Talanta, 1986The use of electrolytic deposition as a separation and preconcentration step in trace metal analysis is reviewed. Both the principles and applications of the technique are dealt with in some detail. Electrolytic preconcentration can be combined with a variety of instrumental techniques.

Aerosol preconcentration on a liquid electrode
Talanta, 1981Electrostatic preconcentration of a dried aerosol is achieved with a water electrode. The system is found to show similar trapping characteristics to those given by wire electrodes, but the subsequent introduction of collected material into a flame atomizer is easier, merely requiring aspiration of the electrode solution after the trapping cycle is ...

1996
Despite the great strides forward in analytical instrumentation that have been made in the last decade, the analyst working in the fields of potable water analysis and environmental analysis of non-saline and saline waters finds that, frequently, the equipment has insufficient sensitivity to be able to detect the low concentrations of substances ...

Microfluidics and Nanofluidics, 2012
A nanofluidic preconcentrator with the capability of rapidly preconcentrating and precisely positioning protein bands in multiple microchannels has been developed for highly sensitive detection of biomolecules. A novel electrical resistive network model is developed to guide the design of the nanofluidic preconcentrator which consists of a PDMS slab ...
