Abstract: An ionisation detector includes a third (fence) electrode (55) between the counter electrode (53) and the sensing electrode (54). The fence electrode (53) is maintained at or near the potential of the sensing electrode (54) and traps charge movement (electrolytic current) along the detector walls associated with condensation and/or contamination within the detector. In a photoionisation detector, the fence electrode is also adapted to trap photo-induced current originating from the cathode (53). Current drawn from the fence electrode (53) provides a measure of the degree of contamination or condensation within the detector and of lamp efficiency.
Abstract translation: 电离检测器包括在对电极（53）和感测电极（54）之间的第三（栅栏）电极（55）。 围栏电极（53）保持在感测电极（54）的电位处或附近，并且沿着与检测器内的冷凝和/或污染相关联的检测器壁捕获电荷运动（电解电流）。 在光电离检测器中，栅极电极还适于捕获源自阴极（53）的光诱导电流。 从栅栏电极（53）吸取的电流提供了检测器内的污染或冷凝程度以及灯效率的量度。

Abstract: A pneumatic manifold comprises at least two substrate layers 26,27,28 wherein at least one layer 28 contains at least one groove which is closed by a second layer 27 to form a gas channel 6; the groove may be rectangular in section. The manifold may comprise three layers 26-28, two layers 27,28 having interconnecting gas channels and the third 26 including a hole communicating with grooves in the first two layers 27,28 and acting as an access port 29 adapted to receive an external module 3. The manifold may be constructed using standard PCB (printed circuit board) construction techniques; by virtue of its PCB construction the manifold also may include conductive electrical tracks and fixing points common to other PCBs and possibly serving electrical pneumatic components.

Abstract: A demountable pellet is disclosed for use as an electrode contact assembly in apparatus such as, for example, a photo ionization chamber or detector. The pellet 1 comprises a base 3 upon which is mounted a plurality of electrodes 18,19,20 arranged in respective spaced parallel planes and having respective contacts areas 23,24,25 protruding from them. A closure 2 for the base 3 has a member 11,12,13 engaging at least one of the electrode contacts. In an unassembled condition of the pellet 1, with the closure 2 separate from the base 3 and each closure member disengaged from its respective electrode contact, the contacts 23,24,25 lie in respective spaced parallel planes. In the assembled condition of the pellet 1 with each closure member engaging its respective electrode contact, at least one of the contacts lies in a plane other than that in which it lay in the unassembled condition of the pellet.
