摘要:
The invention concerns a method for isolating an analyte (1) from an initial sample containing same, on a reactive surface (9) in contact with all or part of the initial sample, characterized in that it comprises the following steps which consist in: 1) forming and/or maintaining a reaction volume entity (2), comprising an internal liquid medium (4), corresponding to all or part of the initial sample, the entity (2) including an interface (5) with an external medium (6), having with the latter a surface tension; 2) applying a temperature difference between at least two thermal points located: a) proximate to and/or b) on the surface and/or c) within said entity (2), said thermal points being respectively different, in terms of temperature and positioning; 3) fixing the analyte (1) on the reactive surface (9), positioned on the path of forced convection generated by the temperature difference.

L'invention concerne également un dispositif de déplacement réversible d'au moins un volume de liquide (10) sous l'effet d'une commande électrique, comprenant des premiers moyens électriquement conducteurs (8), des deuxième moyens électriquement conducteurs (4), et des moyens pour induire un déplacement réversible d'un volume de liquide, depuis les premiers moyens vers les deuxièmes moyens électriquement conducteurs, sans contact avec ces moyens conducteurs lors du déplacement.
摘要:
The invention concerns a device for air/water extraction by semi-humid electrostatic collection, comprising a chamber (7) containing a discharge electrode (1) for generating an ion flow from an ionized gas accumulation surrounding the discharge electrode (1) and a counter-electrode (2), an inlet (3) for mixing air and aerosol to be extracted which contains liquid or solid particles, a steam supply tube (8) and an outlet (4) for cleansed air. The invention is characterized in that the device enables stream to be introduced through said steam supply tube (8) in the gap between the discharge electrode (1) and the counter-electrode (2) so as to form a steam sheath (10) enclosing the discharge electrode over its entire length, such that the treated air is not steam-saturated.
