Gas Chromatography Ion Detector - Types of Ion Detectors

Types of Ion Detectors

  • Flame ionization detector (FID) -- uses a flame to produce ions
  • Electron capture detector (ECD) -- uses bta radiation
  • Photo-ionization detector (PID) -- uses UV light to produce ions
  • Helium ionization detector (HID) -- uses a radioactive source to produce helium ions, which in turn ionize the components
  • Discharge ionization detector (DID) -- uses an electric spark source to produce helium ions, which in turn ionize the components
  • Pulsed discharge detector (PDD) -- similar to a Discharge ionization detector (DID), but uses a different sort of spark

Famous quotes containing the words types of, types and/or detectors:

    Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.
    Stephanie Martson (20th century)

    If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.
    Henry David Thoreau (1817–1862)

    There were metal detectors on the staff-room doors and Hernandez usually had a drawer full of push-daggers, nunchuks, stun-guns, knucks, boot-knives, and whatever else the detectors had picked up. Like Friday morning at a South Miami high school.
    William Gibson (b. 1948)
