Abstract: An injector is configured for injecting a fluidic sample from an injector path into a mobile phase in a separation path between a fluid drive and a sample separation unit of a sample separation device. The injector includes a control unit configured for generating a first overpressure in a blocked first partial path of the injector path by a first pressure source, for generating a second overpressure in a blocked second partial path of the injector path by a second pressure source, for subsequently fluidically coupling the first partial path with the second partial path for generating an expansion stroke for releasing a gas bubble in the injector path, and for rinsing the released gas bubble from the injector path.

Abstract: A device and a method for fitting solar cell contact wires providing a series connection, and which run continuously in a string direction to join a front solar cell wafer and a rear solar cell wafer. The device includes a wire-laying mechanism having a wire feed gripper, a wire transport gripper movable in the string direction relative to the wire feed gripper, a wire-holding gripper to grip and hold the contact wires behind the wafer-holding position for the rear solar cell wafer, and a wire cutter. Once a front solar cell wafer has been positioned, the contact wires are transferred from the wire feed gripper to the wire transport gripper, are advanced in the string direction over the wafer-holding position, are gripped and held by the wire-holding gripper, and are then cut behind the wire-holding gripper by the wire cutter.

Abstract: A sample loading device for loading and injecting a sample of a specimen is provided. The device comprises an injection channel having a sample injection spot, the injection channel adapted for feeding a fluid comprising a specimen. It further comprises an injector for injecting the specimen into the fluid along the injection channel and a separation device adapted for separating a sample from the specimen at the sample injection spot. Furthermore it comprises a control unit adapted for controlling the separation device in response to a detected physical parameter of the fluid.
