    摘要: A thin laminated high transmission electro-optical lens populated with a plurality of apertures in communication with its laminates used to improve the collection, focusing, and selection of ions generated from atmospheric pressure sources, such as electrospray, atmospheric pressure chemical ionization, inductively coupled plasma, discharge, photoionization and atmospheric pressure matrix assisted laser desorption ionization. The laminated lens is made of alternating layers of electrically insulating and metal laminates. The geometry of the lens may be planar or shaped into various curve shapes, any of which act to optimize both the direct current (DC) and alternate current (AC) electric field geometries and strengths across the lens for transferring virtually all the ions from the ion source into an ion-focusing region adjacent and upstream of a high pressure or atmospheric pressure interface to a mass spectrometer, ion mobility analyzer, or combination thereof. Embodiments of this invention are methods and devices for improving sensitivity of mass spectrometry when coupled to high pressure or atmospheric pressure ionization sources.

    摘要: An improved ion sampling tube designed to increase the amount of current delivered into the vacuum system of a mass spectrometer or other gas-phase ion or particle detectors or collectors. A device and method is disclosed that utilizes a tube with a high flow of ion entrained gas passing through the said tube. Said ions are directed from the tubular gas flow through an ion selective aperture and into an adjacent region and subsequently directed into a lower pressure region for detection or collection. The method is useful for enhancing the detection of analytes in solutions that are either nebulized or electrosprayed, and analytes present in gases. The method is also useful for isolating ionic species from the ion source from neutral gases and particles that may interfere or interact with analyte species. The method also decouples the high flow of the atmospheric pressure ion source from the low flow ion transmission into vacuum.
