Abstract: Ion guides for use in mass spectrometry (MS) systems are described. The ion guides are configured to provide a reflective electrodynamic field and a direct current (DC or static) electric field to provide ion beams that are more spatially confined with a comparatively large mass range. Some ion guides are provided between the ion source and the first stage vacuum chamber of the MS system.

Abstract: In some examples, an apparatus may include an advection flow structure including a passage to transport, via advection by a gas flow, an ablated sample from an ablation region to an ionization region.
