Abstract: Within an ion pump, accelerated ions leave the center portion of an anode tube due to the anode tube symmetry and the generally symmetrical electric fields present. The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process.

Abstract: A delivery nozzle for aerosol and solvent includes a nozzle body defining an aerosol passage and a solvent passage therethrough. The aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof. The nozzle body can include a solid, unitary structure with the aerosol and solvent passages both defined through the solid, unitary structure. The inlet end of the nozzle body can include a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage. The solvent passage can define a smaller cross-sectional flow area than that of the aerosol passage.

The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process. In various embodiments, one or more wire internal to the anode structure and having a time-varying electric potential may alter the trajectory of the ions leaving the anode tube, as may the shape of the anode near the ends of the anode tube.
Abstract translation: 在离子泵内，由于阳极管的对称性和大致对称的电场存在，加速离子离开阳极管的中心部分。 阳极管中的表观对称性可以通过使阳极管纵向分段并对每个段施加独立电压而改变。 两个相邻段上的电压可以以不同的速率变化以实现光栅化处理。 在各种实施例中，阳极结构内部并且具有随时间变化的电势的一个或多个导线可以改变离开阳极管的离子的轨迹，阳极的形状可以靠近阳极管的端部。

Abstract: An ion pump includes an evacuateable envelope having a chamber. A first and a second cathode are disposed within the chamber and spaced apart from one another. An anode is spaced apart from and between the first and second cathodes. The anode has an anode body with a textured surface that defines capture regions for fixing material sputtered from the first and second cathodes and controlling size of sputter depositions shed from the anode.

Abstract: In accordance with at least one aspect of this disclosure, a method for identifying a chemical composition includes, collecting a chemical sample and introducing the chemical sample to a detection system, performing, with a differential mobility spectrometer, differential mobility spectrometry on the chemical sample to separate ions within the chemical sample into a first constituent group based on a first analysis characteristic. The method further includes, performing, with an ion mobility spectrometer, ion mobility spectrometry on the first constituent group to separate ions within the first constituent group into a second constituent group based on a second analysis characteristic, and determining an identity of the chemical sample based on ions present within the second constituent group.
