Abstract: In a plasma source configured for producing sample atoms for analysis, such as by optical emission spectrometry or mass spectrometry, a plasma torch includes a torch exit in a chamber. A baffle is positioned between the torch exit and an opposing boundary. The baffle may be positioned and configured to suppress or eliminate vortex shedding in the chamber.

Abstract: An apparatus includes an electromagnetic which supports propagation of an electromagnetic wave in a first direction between a first end thereof and a second end thereof, and an electromagnetic-field shaping structure within the electromagnetic waveguide. The electromagnetic-field shaping structure defines a channel extending from a first aperture in a first wall of the apparatus to a second aperture in a second, opposite, wall. The channel has an axis extending in a second direction which is nonparallel with the first direction. The distance between the first aperture and the second aperture in the second direction is less than the width of the interior region of the waveguide at the first and second ends thereof. In some embodiments, a plasma torch is disposed within the channel. The length of the torch closely matches its interaction region.

Abstract: An ion guide generates a radio frequency (RF) field to radially confine ions to an ion beam along a guide axis as the ions are transmitted through the ion guide. The effective potential of the RF field has potential wells distributed along the guide axis. The RF field is constructed such that the potential wells move in an axial direction toward an exit end of the ion guide.

Abstract: An ion guide generates a multipole radio frequency (RF) field to radially confine ions to an ion beam along a guide axis as the ions are transmitted through the ion guide. The effective potential of the RF field has a magnitude on the guide axis that is independent of axial position along the guide axis, and presents no potential wells on-axis. The ion guide may include a plurality of axially spaced electrodes partitioned into transversely spaced segments. Alternatively, the ion guide may include a plurality of helical electrodes wound about the guide axis.
