Abstract: The invention involves electrospray ionization of dissolved substances at atmospheric pressure in the ion source of a mass spectrometer. A chip with a multitude of spray nozzles is proposed, where each individual spray nozzle is surrounded by several sheath gas nozzles, preferably in a symmetric arrangement, for the jet-like introduction of a sheath gas. A shared attracting-voltage electrode is positioned substantially opposite the spray nozzles. The attracting-voltage electrode may have a tapering (e.g. funnel-shaped) opening above each spray nozzle so that the sheath gas jets are forced to closely envelop the spray jet, which is comprised of ions and very fine droplets. Heavier ions and droplets are thus prevented from discharging on the surfaces of the openings of the attracting-voltage electrode. Special measures can be taken to make all spray nozzles spray uniformly and to supply them with substance peaks from chromatographic or electrophoretic separators as simultaneously as possible.

Abstract: A large variety of electroprocessed capsules can be produced to encapsulate a variety of additives within the subcompartments or substructures of the manufactured capsule. Furthermore, the manufactured capsules can be arranged within a filter of a smoking article during the manufacturing process. By modifying the various parameters that control the electrospraying or electrospinning processes, capsules can be manufactured that vary in composition, in substructural organization, and in dimension. A capsule produced by electrospraying comprises at least one polymeric material that encapsulates or supports the retention of at least one flavorant and/or non-flavorant within the capsule. A polymeric material provides a supporting structure for encapsulating at least one flavorant and/or non-flavorant additive. The capsules that can be produced by various electrospraying processes described below include microcapsules in a micro-scaled range, nanocapsules in a nano-scaled range, and various mixtures of microcapsules and nanocapsules.
