Abstract: An ion mobility spectrometer includes a drift tube, a plurality of sensors arranged at one end of the drift tube that provide signals corresponding to ions impinging on the sensors, and a multi-channel data acquisition system, coupled to each of the sensors, that compensates for delays experienced by ions that are farther from a main axis of drift tube prior to combining the signals from the sensors. The sensors may be electrically biased so that a particular one of the sensors that attracts ions is adjacent to one or more of the sensors that do not attract ions. Signals from adjacent sensors may be subtracted to reduce signal values corresponding to mirror current. The plurality of sensors may be arranged as a honeycomb or as a plurality of concentric circles.

Abstract: An air drying system includes a first air dryer that receives ambient air and provides as output exceptionally dry air having a moisture concentration of approximately 16 ppm or below, a second air dryer that receives ambient air and provides as output exceptionally dry air having a moisture concentration of approximately 16 ppm or below, and a valve coupled to and selectively switching between output from the air dryers to provide exceptionally dry air, where one of the first and second air dryers is automatically regenerated while the valve switches to provide exceptionally dry air from an other one of the first and second air dryers. The air dryers may remove moisture from ambient air by cooling the ambient air to approximately −57° C. Each of the air dryers may include a heat sink section, a cooling section (possibly with cooling elements), and an air flow section.
