Pass energy

{
  "id": "MLC-T-CHM-008526",
  "term": "Pass energy",
  "field": "Chemistry",
  "definition": "The kinetic energy at which ions or electrons are allowed to traverse the analyzer section of an electron or ion energy spectrometer. By setting this energy, the analyzer selects particles within a narrow energy window, thereby determining the energy resolution of the measurement. A lower pass energy generally results in higher energy resolution but lower signal intensity.",
