A device for collecting particles present in a gas or gas mixture, including a component, a collection zone disposed on the component, on which said particles are deposited, collection device configured to force said particles to be deposited against the collection zone, a fluidic elution circuit arranged in said component to elute the particles present in the collection zone.

Device for collecting and analyzing airborne particles

An electrostatic collector including: a collection chamber delimited by a tubular wall oriented along a first axis; a collection electrode configured to be disposed inside the collection chamber against the wall; a discharge electrode, of elongate form, that extends along the first axis and includes an end, in a shape of a tip, the end being disposed opposite the collection electrode; a first part of a first diameter, emerging on the tip-shaped end, a second part of a second diameter, the second diameter being greater than or equal to twice the first diameter, the second diameter for example being between 2 and 6 times the first diameter; and a sudden widening, extending between the first part and the second part.

Electrostatic collector

An electrostatic collector is provided, including a collection chamber, delimited by a tubular wall, and a support holding an electrode in position in the collection chamber and for removing it from the collection chamber, the support including a guide, passing transversally through the collection chamber, the first and second ends of which are fixed to the wall, the guide including a through opening configured to hold the electrode; a first attachment element, including at least one electrically conducting part, that will extend at least partly in the guide, from the first end towards the opening; and a second attachment element, including at least one electrically insulating part, that can move in translation in the guide from the second end towards the opening and from the opening towards the second end.

An electrostatic collection device of particles in suspension in a gas including a collecting chamber with a collecting wall, part of which forms a collecting electrode. The collecting electrode faces a discharge electrode in the form of a wire, so as to create a corona discharge between the discharge electrode and the collecting electrode, the collecting wall extends to the periphery of the discharge electrode. The discharge electrode is maintained at a first end by a first holder and at the second end by a second holder, both holders made of electrically insulating material(s). At least one traversal wall protrudes from the collecting wall, and has a shape adapted to deflect the path of a liquid present in the gas and flowing on the collecting wall to the transversal wall such that it does not come into contact with the second holder.

Electrostatic collection device of particles in suspension in a gaseous environment

The present invention relates to a device for the vaporization of a liquid, said device comprising: a reservoir capable of containing a liquid to be vaporized, a heating element capable of heating the liquid in order to vaporize the liquid, a capillary pump capable of pumping the liquid contained in said reservoir to said heating element by capillary pumping, and a capillary barrier arranged along a capillary pumping direction of the liquid to be vaporized downstream from the capillary pump, said capillary barrier being capable of preventing the non-vaporized liquid from escaping from the device.

Evaporation device

A device for collecting particles in air comprising a collecting chamber (), a capillary tube () whereof one end () terminates in the chamber (), a collecting electrode, the capillary tube () containing polarisable liquid. Sufficient difference in voltage is applied between the liquid and the collecting electrode () for a corona effect between the drop of liquid at the end of the capillary tube () and the collecting electrode () and the spraying of the drop () by electrospray. The corona discharge causes flow of air through the collecting chamber () and the electrospray ensures wetting of the collecting electrode ().
