Low pressure electrical discharge

{
  "id": "MLC-T-CHM-013243",
  "term": "Low pressure electrical discharge",
  "field": "Chemistry",
  "definition": "A phenomenon where an electric current passes through a gas at reduced pressure, causing the gas to ionize and emit light. This process involves collisions between electrons and gas atoms, leading to excitation and subsequent photon emission. It is employed in analytical techniques like atomic emission spectrometry for elemental analysis.",
