Abstract: Certain configurations of mass spectrometer components are described herein that comprise one or more mass spectrometer programmable elements. In some instances, the mass spectrometer programmable element can be configured as an electrode that can function independently of any underlying substrate or component. Ion guides, lenses, ion switches, mass analyzers and other components of a mass spectrometer are described which comprise one or more mass spectrometer programmable elements.

Abstract: A system for cooling an inductively coupled plasma (ICP) instrument includes: the ICP instrument; a pump in fluid communication with the instrument via a first conduit; and a micro-channel heat exchanger in fluid communication with the instrument via a second conduit, and in fluid communication with the pump via a third conduit. The pump is configured to generate a pump outlet pressure of coolant that exceeds a back pressure of the instrument such that a pressure of the coolant traveling through the second conduit and into the heat exchanger is less than or equal to 5 pounds per square inch (psi) above atmospheric pressure, as measured at an inlet to the heat exchanger.

Abstract: An ion guide includes a plurality of curved electrodes arranged along a curved central axis. The plurality of electrodes define a curved ion guide region, with the curved ion guide region beginning at an ion entrance and ending at an ion exit. The ion guide includes an ion deflecting device configured to apply a radial DC electric field across the ion guide region and along the curved central axis. The ion guide region has a radius of curvature that varies along the curved central axis, and the radius of curvature is at a maximum at the ion entrance and decreases along the curved central axis toward the ion exit.
