    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： A supply element for a microfluid microchip that can be used for chemical analysis has supply lines or reservoirs that serve to supply the microchip with substances or reagents. Both ends of the supply lines are sealed to prevent the substances from leaving the supply element or contaminating the contained substances before an experiment. In addition, supply lines are provided that are designed as contact pins to transfer electrical voltage from the supply device to the microchip and serve to offer the required electrical potential for moving the substances corresponding to the microfluid structure of the microchip. The supply element permits the microchip to be easily supplied according to the cited requirements with the required substances for a respective experiment and, in particular, has the advantage that only the supply element itself directly contacts the microchip and can be soiled or worn. The supply element can also be advantageously exchanged with a new element between individual experiments to advantageously reduce to a minimum the danger of contamination by substances on the microchip.
