    • The invention describes a method of manufacturing an electrode(1) for a gas-discharge lamp, which method comprises forming an electrode shaft(10); forming a coil(2) over a winding length (L W );arranging the coil(2) on the electrode shaft(10); and melting material of the coil(2) such that, when the melted coil material has re-solidified, the solidified material(30,31) comprises a one-piece shell(3), which one- piece shell(3) comprises a fused portion(30) over a fraction (L T ) of the winding length (L W ) and a mantle portion(31) over a remainder (L B ) of the winding length (L W ). The invention further describes an electrode(1) for a gas-discharge lamp, which electrode(1) comprises an electrode shaft(10); a coil(2) arranged on the electrode shaft(10) over a winding length (L W ); and a one-piece shell(2) comprising re-solidified material of the coil(2), which one-piece shell(3)comprises a fused portion(30) over a fraction (L T ) of the winding length (L W ) and a mantle portion(31) over a remainder (L B ) of the winding length (L W ). The invention also describes a gas-discharge lamp(6) comprising a burner(4) enclosing a discharge vessel(40), a first electrode(1) and a second electrode(1), wherein the electrodes(1) are arranged to protrude into the dis- charge vessel(40) from opposite sides of the discharge vessel(40), wherein at least one of the electrodes(1) comprises an electrode(1) according to the invention.

    • A pre-concentration device is provided for a gas analysis system (10) for collecting molecular contamination in a vacuum environment (11). The pre-concentration device (13) comprises a hollow element (15) having an entrance opening (20) for receiving molecules from the vacuum environment (11) in a collection phase, a gas outlet for transferring collected molecules to a vacuum compatible detector or second preconcentration device in a transfer phase. The device has an inner wall for adsorbing molecules in the collection phase and desorbing molecules in the transfer phase. The device has a filler element (14) that is movable from a first position outside the hollow element in the collection phase to a second position inside the hollow element in the transfer phase which second position leaves open a transfer channel to the gas outlet along the inner wall. Advantageously, the device enables transferring of the organic or inorganic contaminants collected in the device under vacuum conditions, and requires a minimal amount of ultra pure gas for the transport of the contaminants to a detector or further a concentration device, which lowers the lower limit of detection.
    • 提供了用于在真空环境(11)中收集分子污染物的气体分析系统(10)的预浓缩装置。 预浓缩装置(13)包括具有入口(20)的中空元件(15),用于在收集阶段从真空环境(11)接收分子,气体出口用于将收集的分子转移到真空兼容的检测器或 第二预浓缩装置在转移阶段。 该装置具有用于在收集阶段吸附分子的内壁和在转移阶段解吸分子。 该装置具有填充元件(14),其可以在收集阶段中的中空元件外部的第一位置移动到转移阶段中的中空元件内部的第二位置,该第二位置沿着沿着该中空元件的第二位置打开沿着 内墙。 有利地,该装置能够在真空条件下转移收集在装置中的有机或无机污染物,并且需要最少量的超纯气体用于将污染物输送到检测器或另外的浓度装置,这降低了下限 检测。
