MASS DEPENDENT AUTOMATIC GAIN CONTROL FOR MASS SPECTROMETER |
| 摘要 |
Systems and methods for automatic gain control in mass spectrometers are disclosed. An exemplary system may include a mass spectrometer, comprising a lens configured to receive a supply of ions, and a mass analyzer. The mass analyzer may include an ion trap for trapping the supplied ions. The mass analyzer may also include an ion detector for detecting ions that exit the ion trap. The lens may focus the ions non-uniformly based on mass of the ions to compensate for space charge effects reflected in a measurement output of the mass spectrometer. |

1. A mass spectrometer, comprising:
a lens configured to receive a supply of ions; and a mass analyzer downstream of the lens, the mass analyzer having:
an ion trap for trapping the supplied ions; andan ion detector for detecting ions that exit the ion trap, wherein the lens focuses the ions non-uniformly based on the mass of the ions to compensate for space charge effects reflected in a measurement output of the mass spectrometer. |
