MULTIMODE IONIZATION SOURCE

摘要

The present invention provides an apparatus and method for use with a mass spectrometer. The multimode ionization source (2) of the present invention provides one or more atmospheric pressure ionization sources (3, 4). These sources may be electrospray, atmospheric pressure chemical ionization and/or atmospheric pressure photoionization source and are used for ionizing molecules from a sample (21). A method of producing ions using the multimode ionization source (2) is also disclosed. The apparatus and method provide advantages of the combined ion sources without the inherent disadvantages of the individual sources.
