4450 Tandem PID/FID

Experience the convenience and flexibility of the Model 4450 Tandem Photoionization Detector/Flame Ionization Detector (PID/FID): a patented combination gas chromatography (GC) detector incorporating the Model 4430 PID and Model 4410 FlD.

• Overview

  Our dynamic duo Model 4450 Tandem PID/FID offers the goodness of two detectors packed into one convenient instrument. Together, the detectors produce simultaneous chromatograms for aromatics and aliphatics, eliminating the need for separate analysis.

  Tandem PID/FID Features:

  • Patented design uses only one GC detector port
  • Tandem design acquires two simultaneous chromatograms from a single injection
  • Elimination of transfer lines between detectors improves peak shape and performance
  • System uses GC electronics or OI Analytical’s dual channel electrometer
