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
