ATMOSPHERIC PRESSURE IONIZATION INLET FOR MASS SPECTROMETERS

摘要

Methods and systems for mass spectrometry and more particularly to an interface providing charged particles to a mass spectrometer are described herein. In some examples, the interface comprises a capillery extending from an atmospheric pressure region to vacuum chamber at a pressure of 4mbar or less. The vacuum chamber includes an extracting aperture positioned at a location of a turbulent region in the gas ions to a vaccum region at about 1,3.10-2mbar or less
