Mass discrimination

{
  "id": "MLC-T-CHM-006975",
  "term": "Mass discrimination",
  "field": "Chemistry",
  "definition": "The phenomenon in mass spectrometry where the detection efficiency or transmission efficiency of ions varies with their mass-to-charge ratio. This can lead to an inaccurate representation of the relative abundances of different ions in a sample. Mass discrimination effects must be accounted for, often through calibration, to obtain accurate quantitative results.",
