The flashcards below were created by user saitclt on FreezingBlue Flashcards. What would you like to do?


  1. TCD
    Thermal Conductivity Detector
  2. FID
    Flame Ionization Detector
  3. ECD
    Electron Capture Detector
  4. PID
    Photoionization detector
  5. FPD
    Flame photometric detector
  6. NPD
    Nitrogen Phosphorus Detector
  7. Which type of GC detector is concentration sensitive? (this means the flow of carrier gas does not effect detection)
    TCD
  8. Name one type of detector which is mass sensitive (carrier gas flow is required for detection)
    FID
  9. Which detector uses emission spectra?
    FPD, flame photometric. It detects emission of S and P as they burn in an air:H2 flame
  10. Which detector uses a thermionic bead to produce ions of N and P -containing compounds?
    NPD (nitrogen phosphorus detector)
  11. Which detector includes a beta emitter (electron emitter) such as Ni-63?
    ECD
  12. Which detectors are specifically useful for pesticides?
    • ECD (since pesticides are electronegative)
    • NPD
  13. Which detector might you use specifically for pollutants containing S and P?
    FPD (flame photometric detector)
  14. Would you use split or splitless injection for trace analysis?
    splitless
  15. Which term of the Van Deemter equation doesn't apply to capillary columns?
    A (eddy diffusion or multipath)
