摘要： The invention provides a multipole device for a mass spectrometer system. In general, the multipole device contains a plurality of conductive rods each comprising a conductive layer, a resistive layer, and an insulative layer between the conductive and resistive layers. The invention finds use in a variety of applications, including ion transport, ion fragmentation and ion mass filtration. Accordingly, the invention may be employed in a variety of mass spectrometer systems.

摘要： An atmospheric pressure ion source, e.g. for a mass spectrometer, that produces ions by atmospheric pressure photoionization (APPI). It includes a vaporizer, a photon source for photoionizing vapor molecules upon exit from the vaporizer, a passageway for transporting ions to, for example, a mass spectrometer system, and a means for directing the ions into the passageway. The center axis of the vaporizer and the center axis of the passageway form an angle that may be about 90 degrees. Included in the invention is a method for creating ions by atmospheric pressure photoionization along an axis and directing them into a passageway oriented at an angle to that axis.
