摘要： An electrospray ionization (ESI)-mass spectrometer analysis systems include an ESI device with at least one emitter configured to electrospray ions and a mass spectrometer in fluid communication with the at least one emitter of the ESI device. The mass spectrometer includes a mass analyzer held in a vacuum chamber. The vacuum chamber is configured to have a high (background/gas) pressure of about 50 mTorr or greater during operation. During operation, the ESI device is configured to either; (a) electrospray ions into a spatial region external to the vacuum chamber and at atmospheric pressure, the spatial extent being adjacent to an inlet device attached to the vacuum chamber, the inlet device intakes the electrosprayed ions external to the vacuum chamber with the mass analyzer and discharges the ions into the vacuum chamber with the mass analyzer; or (b) electrospray ions directly into the vacuum chamber with the mass analyzer.
