Gas Chromatography Detectors
  

 
  • 16 detector types to choose from
  • Up to 4, 5, or 6 detectors can be installed on one GC
  • Several detectors can be run in series for multiple chromatograms from one injection
  • Equipped with a thermostatted heater block for temperature stability
  • Internal amplifier electronics
  • Electronic pressure controlled (EPC) support gases, such as hydrogen and air for the FID detector
  • All detectors require factory installation
Catalytic Combustion Detector - CCD
  • Hydrocarbon and hydrogen selective
  • Detects down to 500ppm
  • Gas-less operating capability
  • Inexpensive and rugged
  • Built-in spare!
Thermal Conductivity Detector - TCD
  • "Universal" detector
  • Detects from 1% down to 200-500ppm
  • Easily replaceable filaments
  • Thermostatted up to 275°C
Flame Ionization Detector - FID
  • Hydrocarbon Selective
  • Robust, linear, stable
  • Detects down to 1ppm
  • Unique ceramic ignitor can run HOT continuously to keep flame lit
Dry Electrolytic Conductivity Detector - DELCD
  • Non-radioactive alternative to ECD!
  • High sensitivity - detects down to 10ppb
  • Selective to cholorinated and brominated molecules
  • Best used with headspace or Purge & Trap injectors
  • Can be combined with FID, NPD, or TID detectors
  • Spare detector cell included
Combination Flame Ionization Detector and Dry Electrolytic Conductivity Detector - FID/DELCD
  • The FID detects hydrocarbons and the DELCD identifies which are halogenated
  • No electrolytes needed for the DELCD
  • High and low sensitivity modes
  • Detects to the low ppm range
  • Spare detector cell included
Helium Ionization Detector - HID
  • Universal (except neon)
  • Detect from 1-2% down to 10ppm
  • Requires only helium carrier and make-up gas
  • Perfect complement to the TCD!
Photo Ionization Detector - PID
  • Responds to molecules with carbon double bonds and aromatics
  • Sensitive (down to 10ppb) and non-destructive
  • Mandated in several EPA methods
  • Extremely long lamp life!
Nitrogen-Phosphorus Detector - NPD
  • Very selective to nitrogen and phosphorus
  • Detects down to 100ppb
  • Exceptionally rugged NPD bead
  • Similar in design to the SRI FID
Combination Nitrogen-Phosphorus Detector and Dry Electrolytic Conductivity Detector - NPD/DELCD
  • Ideal for pesticide screening
  • NPD detects organo-phosphorus (OPP)
  • DELCD detects chlorinated species
  
Thermionic Ionization Detector - TID
  • Highly selective to nitro functional groups
  • Also responds to chlorinated phenols
  • Detects down to 1ppb
  • Convenient bead design
  • Can be run gas-less in the field!
Flame Photometric Detector - FPD
  • Bandpass filters for sulfur or phosphorus
  • Use the dual FPD for simultaneous sulfur and phosphorus detection
  • Detects sulfur compounds to 200ppb, phosphorus compounds down to 10ppb
  • Use the FPD/FID or Dual FPD/FID for simultaneous hydrocarbon speciation
Combination Flame Photometric Detector and Flame Ionization Detector - FPD/FID
  • Combines all the features of the FPD and the FID detectors
  
Dual Flame Photometric Detector - Dual FPD
  • All the features of the FPD detector
  • Dual wavelength for simultaneous sulfur and phosphorus response
 
Combination dual Flame Photometric Detector and Flame Ionization Detector - FID dual FPD
  • Dual FPD with sulfur and phosphorus filters and FID Collector electrode
  
Electron Capture Detector - ECD
  • Thermostatted from ambient to 375°C
  • Offers extreme sensitivity - down to 10ppt
  • Detects electronegative compounds
  • Mandated for pesticides and PCBs
Reduction Gas Detector - RGD
