- Describe and explain what fields are mass spectrometry used in?how is mass spectrometry important in biology?Which of the following statements are false for the time-of-flight mass spectrometer ? Light fragments travel faster than heavier fragments. A strong electric field is present in the tube by positioning a high-voltage metal grid in the path. Uses a magnetic field. Fragments are separated based on how fast they move through a drift tube. Signal is measured versus time, and then translated to a mass spectrum.
