摘要： A membrane structure for gas separation, a degassing device having such a membrane structure, and also method for production of the same are proposed. A porous carrier layer is joined flat to a thin polymer membrane, in particular made of amorphous PTFE. In particular, the polymer membrane is produced on or from the carrier layer. This makes possible a simple and inexpensive structure and also an effective gas separation. Particularly preferable, the polymer membrane is formed by applying a polymer solution in the liquid state to the carrier layer and drying it.

摘要： A process and a device for separating and exhausting gas bubbles from a flowing liquid, especially in a microfluidic system, are proposed. Radial deflection of the liquid, a preferably annular deaeration chamber from which gas can escape through gas separation material, and a following discharge filter are characteristic. The discharge filter is made of a hydrophilic material which forms pores or small channels. Optionally, there is an inlet filter of the corresponding material upstream of the deaeration chamber.

摘要： In the swell-welding according to the invention of two bodies, of which at least one body consists of plastic, the connection surface of the plastic body is firstly exposed to a gas which contains the vapor of a swelling agent for the plastic. The plastic body reversibly swollen at the surface is welded to the other body by pressing onto one another, and the pressed-together bodies are conditioned. In all process steps, the temperature of the bodies to be connected is below the glass transition temperature of the plastic. No auxiliary substance remains in the welded body. The flush connection produced by swell welding is durable and strong.

摘要： A microfluidic network having at least one channel which is open on the top side and in which one end of at least one hollow fiber is inserted and a process for making it. For this it is provided that the outside dimensions of the hollow fiber are matched to the inside dimensions of the channel, capillary channels being formed between the hollow fiber and the walls of the channel. The network is covered with a cover film or plate which closes the channel and preferably fixes the hollow fiber temporarily in the channel, and the capillary channels are filled with a fluidically sealing cement. In the area of the inserted end of the hollow fiber, a capillary stop structure is formed so that the cement as it is added it cannot seal the inserted open end of the hollow fiber.

摘要： An apparatus for degassing liquids comprises a cavity through which liquid is conducted, with gas being removed from the liquid through at least one of the limiting faces of the cavity by providing on the side of the face distal to the cavity a smaller pressure than within the cavity. The apparatus is characterized in that the limiting face between the cavity and the region having reduced pressure compared to the cavity is formed by at least one thin membrane, having a thickness of less than about 10 micrometers, and in that a porous support structure for supporting the membrane is provided. The degasser can be miniaturized and integrated into a liquid chromatograph.

摘要： In a method for joining two or more solid parts, a foil is provided between the two parts, the foil is heated to an elevated temperature by means of a thermode such that it becomes soft, and then the foil is cooled down below the elevated temperature, thus providing a permanent connection. The method can be used for bonding a gas-permeable membrane to a housing such as to produce a liquid chromatography degasser. The bonding method ensures that no unwanted substances are released when liquid comes into contact with the bonding region.
