The invention relates to a reaction chamber (10), which comprises a cylindrical vessel (11), with, at one end (12), at least one inlet or outlet tube or lead-through (20) fitted with a valve (25) for a liquid or gaseous component. The other end (13) of the vessel is open. The reaction chamber further comprises a plunger (14), which performs a reciprocating movement within the cylindrical vessel in axial direction through the open end (13) of the vessel. The plunger tightens against the inner wall of the cylindrical vessel, and has at least one channel (15), in substantially axial direction, fitted with a valve (45) or connected to a tube (40) fitted with a valve. The invention relates also to an assay method based on the use of the said reaction chamber.
L'invention concerne une chambre de réaction (10) comprenant un récipient cylindrique (11), qui comporte, à une extrémité (12), au moins un tube d'entrée, ou un tube de sortie ou un passage (20) pourvu d'une valve (25) pour un composé liquide ou gazeux. L'autre extrémité (13) du récipient est ouverte. La chambre de réaction comporte en outre un piston (14) qui effectue un mouvement d'aller et de retour à l'intérieur du récipient cylindrique dans la direction axiale, par l'extrémité ouverte (13) dudit récipient. Le piston est en relation d'étanchéité avec la paroi interne du récipient cylindrique et il possède au moins un canal (15), dans une direction sensiblement axiale, pourvu d'une valve (45) ou connecté à un tube (40) pourvu d'une valve. L'invention concerne également une méthode de dosage basée sur l'utilisation de ladite chambre de réaction.
