Abstract
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.
