Micro-electromembrane extraction across multiple aqueous and organic phases for selective pretreatment of raw biological samples
Kubáň, Pavel ; Boček, Petr ; Seip, K. F. ; Gjelstad, A. ; Pedersen-Bjergaard, S.
Micro-electromembrane extraction (μ-EME) across multiple aqueous and organic\nsolutions was developed for selective extractions of various analytes from untreated\nbiological samples. The novel approach requires μL volumes of samples and organic\nsolvents, which form consecutive immiscible plugs in a transparent polymeric capillary\nand the extraction process is accelerated by application of d.c. voltage. Number of the\nplugs, their composition, volume and sequence in the extraction capillary can be chosen\nspecifically for each particular application and high variability and selectivity of the\nextraction process can be achieved. In this contribution, we demonstrate suitability of\na five-phase μ-EME system for simultaneous extractions of cations and anions from\nurine and for selective extractions of basic analytes based on their acid-base strength\nfrom plasma.

J. ; Farrell, W.M. ; MacDowall, R. J. ; Sternovsky, Z. ; Horanyi, M. ; Delory, G.T. ; Turin, P.
A complete set of scientific instrumentation for the L-DEPP dust, plasma and waves package for the ESA Lunar Lander mission has been proposed and fully assessed with respect to the system and scientific requirements derived by ESA and the L-DEPP project team. The preliminary design from the system level down to the individual sensors is presented.
