    • Generally, the present invention provides a recirculating filtration system for use with a transportable ion mobility spectrometer in gas chromatography applications. The transportable recirculating filtration system comprises a pump and a set of filters and flow sensors connected to an ion mobility spectrometry sensor having a gas chromatograph column at its inlet. The IMS sensor's outlet flow is cleaned by the filters and recirculated by the pump back into the IMS sensor as the carrier fluid stream flow. A portion of the IMS sensor's outlet flow equal to the amount of flow introduced into the sensor as the sample is exhausted from the filtration system to maintain a constant total flow volume through the system as the sample is being analyzed. Preferably, the multicapillary column is sealed to a heated transfer line leading to the sample stream inlet of the IMS sensor. The transfer line is preferably maintained at a temperature 10.degree. C.-40.degree. C. above that of the multicapillary column in order to ensure that analyte species will not adsorb on the walls of the transfer line instead of entering the sample stream inlet of the IMS sensor. The transfer line can be optionally configured with a flow smoothing insert to produce a laminar flow profile throughout the volume between the transfer line outlet end and the IMS sensor housing upon exit of the carrier flow stream from the flow smoothing insert.
    • 通常,本发明提供了一种在气相色谱应用中与可运输离子迁移谱仪一起使用的再循环过滤系统。 可运输的循环过滤系统包括泵和一组连接到其入口处具有气相色谱柱的离子迁移谱传感器的过滤器和流量传感器。 IMS传感器的出口流被过滤器清洁,并随着载体流体流的流动而被泵再循环回到IMS传感器中。 随着样品从过滤系统排出,IMS传感器的出口流的一部分等于引入传感器的流量,以便在分析样品时保持通过系统的恒定总流量。 优选地,多毛细管柱被密封到通向IMS传感器的样品流入口的加热的输送管线。 传输线优选保持在高于多毛细管柱的温度10℃-40℃的温度下,以确保分析物种不会吸附在输送管线的壁上,而不是进入 IMS传感器。 输送管线可以可选地配置有流动平滑插入件,以在从流动平滑插入件离开载体流动流时,在传送线出口端和IMS传感器外壳之间的整个体积中产生层流分布。

    • A solenoid operated circuit breaker trip device has a base defining a guide channel and an actuator that slides in the guide channel and interacts with a contact breaking mechanism having a trip bar operable to make or break electrical contacts. A spring biases the actuator toward the trip bar. A solenoid on the base electromagnetically displaces a plunger along a linear path and is coupled to a trigger having a latching surface that holds or releases the actuator. The guide channel runs parallel to the path of the plunger, adjacent the solenoid. The trigger is L-shaped and pivoted on a pivot pin between two legs of its L-shape, on an axis transverse to the path of the plunger. One of the two trigger legs is coupled to the plunger, and the other has an engagement surface that is moved behind a complementary surface of the actuator to selectively block its displacement. The base can be a slotted frame attached to the solenoid or a molded housing having an interior cavity for receiving the solenoid. A return spring urges the trigger toward the latching position.
    • 螺线管操作的断路器跳闸装置具有限定引导通道的基部和在引导通道中滑动的致动器,并且与具有可操作以产生或断开电触点的跳闸杆的触点断开机构相互作用。 弹簧将致动器偏压到跳闸杆。 基座上的螺线管电磁地沿着线性路径移动柱塞并且联接到具有保持或释放致动器的闩锁表面的触发器。 引导通道平行于柱塞的路径平行,与螺线管相邻。 触发器是L形的,并且在横向于柱塞的路径的轴上的枢轴销上枢转在L形的两个腿之间的枢轴销上。 两个触发器腿中的一个联接到柱塞,另一个具有接合表面,该接合表面在致动器的互补表面后移动以选择性地阻挡其位移。 基座可以是连接到螺线管的开槽框架或具有用于容纳螺线管的内部空腔的模制外壳。 复位弹簧将扳机推向闩锁位置。
