ION SOURCE SYSTEM FOR ATMOSPHERIC PRESSURE INTERFACE, AND MASS SPECTROMETER

摘要

Provided is an ion source system for an atmospheric pressure interface, comprising an atmospheric pressure ion source (1), the atmospheric pressure ion source (1) being connected downstream to a vacuum ion source (2). Also provided is a mass spectrometer, using the present ion source system as an ion source. The present ion source system uses a combination of the atmospheric pressure ion source (1) and the vacuum ion source (2), is suitable for test samples having a variety of forms, and performs secondary ionization on a sample to be tested, thus ensuring ion transmission efficiency. The present mass spectrometer significantly increases ion transmission efficiency, thus enabling continuous introduction of samples and testing, and increasing the scanning speed of the spectrometer, particularly suitable for miniaturized spectrometers.
