摘要: A valve of the membrane valve type comprises a valve body with two fluid flow channels (5, 5') separated by a land portion which forms a valve seat (6) having a sealing surface for co-operation with a flexible membrane (7) mounted over a duct (8) which opens in front of the valve seat and is arranged for fluid pressure actuation of the membrane between a closing position, where the membrane (7) sealingly contacts the valve seat (6), and an opening position where there is a flow channel communicating space ( 11) between the valve seat (6) and the membrane (7). The valve is characterized in that the sealing surface of the valve seat (6) comprises (i) a primary sealing surface (10) located nearest and facing the membrane, and (ii) a secondary sealing surface (12, 12') provided on each fluid channel side of the valve seat, so that when the valve is closing, the membrane (7) successively seals against the primary sealing surface (10) and the secondary sealing surfaces (12, 12'), and, inversely, when the valve is opening, the member (7) is successively separated from the secondary sealing surfaces (12, 12') and the primary sealing surface (10).

摘要: Methods and devices are provided for controlling a fluid flow over a sensing surface within a flow cell. The methods employ laminar flow techniques to position a fluid flow over one or more discrete sensing areas on the sensing surface of the flow cell. Such methods permit selective sensitization of the discrete sensing areas, and provide selective contact of the discrete sensing areas with a sample fluid flow. Immobilization of a ligand upon the discrete sensing area, followed by selective contact with an analyte contained within the sample fluid flow, allows analysis by a wide variety of techniques. Sensitized sensing surfaces, and sensor devices and systems are also provided.

摘要: The invention provides surface plasmon resonance-mass spectroscopy for the rapid, sensitive and accurate investigation of molecular interactions coupled with the identification and quantification of the same. Methods of the invention include capturing an analyte present within a sample by an interactive surface layer on a real-time interaction analysis sensor, analyzing the analyte by surface plasmon resonance while the analyte is captured by the interactive surface layer, and identifying the captured analyte by desorbing/ionizing the analyte from the interactive surface layer while under vacuum within a mass spectrometer. Devices of the invention include a transparent material, a conductive material capable of supporting surface plasmon resonance affixed to the transparent material, an interactive surface affixed to the conductive material, and a means for exposing the interactive surface to the interior of a mass spectrometer without breaking the vacuum therein.
