Abstract: The invention relates to a device for analysing the effects of at least one parameter related to a volatile substance on a living test system, characterised in that it comprises: an enclosure (1) composed of a first compartment (20) comprising a gas inlet (21) and a gas outlet (22), and a second compartment (30) in which the test system and the volatile substance are located, the first (20) and second (30) compartments communicating with each other through an opening (11) fitted with a semi-permeable membrane (40) adapted to limit a flow of volatile substance from the second compartment (30) to the first compartment (20) in a determined manner, while allowing a gas flow from the first compartment (20) to the second compartment, (30), and the second compartment (30) being hermetically sealed such that the only exchanges with an outside medium take place towards the first compartment (20), through the membrane (40).

Abstract: The present invention relates to self-supporting dynamic polymer membranes (called “dynamer” membranes) of the polyimine type, to their method of preparation and to their use in separation processes, especially for separating gaseous CP species.

Abstract: The invention relates to an equipment and a system for processing a gaseous mixture by permeation. The equipment of the invention includes m*n separation modules Pij, n and n being natural integers higher than or equal to 2, i being a natural integer from 1 to m, and j is a natural interger from 1 to n. Each of the separation modules P1 includes a permeate inlet Epij, the permeate inlet Ep11 of the separation module P11 corresponding to the F inlet for supplying the gaseous mixture into said equipment, a permeate outlet Spij and a retentate outlet Srij. Furthermore, the permeate outlet Spij is connected to the permeate inlet Epi+1j of the separation module Pj+1j, and the retentate outlet Srij is connected to the permeate inlet Epij+1 of the separation module Pij+1. The equipment does not use any intermediate recycling.

Abstract: The present invention relates to the use of a hydrophilic, biocompatible and biodegradable elastomer membrane or film for the selective separation of a gas mixture. Accordingly, processes for selective gas separation of a gas mixture are provided in which a gas mixture is contacted with such a membrane such that a selective portion of the gas mixture passes through the membrane.

Abstract: The invention concerns a membrane for selective gas separation. The membrane consists of an ethylene oxide copolymer or a polymeric material obtained by crosslinking such a copolymer. Said copolymer is characterised in that it consists of at least 30% in number of —CH2CH2O— units derived from ethylene oxide, and at least 2% in number of —CHR—CH2O— units derived from an oxirane bearing a crosslinkable substituent R and/or of —CHR1—CH2O— units derived from an oxirane bearing a non-crosslinkable substituent R1. The membranes are particularly useful for separating hydrophilic gases contained in a gas mixture.
