摘要： The present invention provides an apparatus and method for use with a mass spectrometer. The multimode ionization source of the present invention provides one or more atmospheric pressure ionization sources (e.g., electrospray, atmospheric pressure chemical ionization and/or atmospheric pressure photoionization) for ionizing molecules. A method of producing ions using the multimode ionization source is also disclosed. The apparatus and method provide the advantages of the combined ion sources without the inherent disadvantages of the individual sources. In an embodiment, the multimode ionization source includes an infrared emitter enclosed in an inner chamber for drying a charged aerosol. ESI/APCI multimode sources may include a corona needle shield and/or an auxiliary electrode.

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.

摘要： The invention relates to an apparatus for forming liquid droplets, such as a micro nebulizer, useful for preparing samples for subsequent analysis via MS, AA, ICP, CE/MS, and similar analytical systems. The apparatus has a mechanically stabilized inner microtube or needle, thereby ensuring controllably uniform droplet size. The mechanical stabilization is provided by securing the inner microtube or needle, such as by narrowing the inner diameter of the outer microtube or otherwise narrowing the annular intermediate space between the inner and outer microtubes for a predetermined length. Thus, the inner microtube is secured in a centered or otherwise predetermined fixed radial position, with minimum perturbation of the fluid flow. Further, a tip, when coupled with the exit end of the outer microtube, provides a region in which the sheath fluid flow in the outer microtube stabilizes prior to both exiting the tip and colliding with the liquid analyte exiting the inner microtube.
