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
