摘要： A time-of-flight mass spectrometer has a first electrode, a second electrode spaced apart from the first electrode, a third electrode arranged between the first and second electrodes. The third electrode reserves a space for ions to travel between the first and second electrodes. The time-of-flight mass spectrometer further includes a sample probe disposed proximate the first electrode and adapted to hold a sample, and a detector disposed proximate the second electrode. The first electrode is adapted to be connected to a voltage source to cause a difference in voltage between the first and second electrodes to provide an electric field therebetween that changes non-linearly along an ion path between the sample probe and the detector for accelerating ions to be detected.
