摘要: Systems and methods for automatic gain control in mass spectrometers are disclosed. An exemplary system may include a spectrometer, comprising lens configured to receive supply of ions, analyzer. The analyzer an ion trap trapping the supplied ions. also detector detecting ions that exit trap. focus non-uniformly based on compensate space charge effects reflected measurement output spectrometer. method focusing beam into obtaining spectrum identifying characteristic spectrum. further defocusing identified characteristic, wherein is divert lighter away from entrance aperture. defocused generated sample.
