The OI Analytical Model 4450 Tandem Photoionization Detector/Flame Ionization Detector (PID/FID) patented system utilizes a combined gas chromatography (GC) detector found in both the Model 4430 PID and Model 4410 FlD systems.
As a result, this dynamic model offers users with the convenience of two detectors that are packed into a single instrument. Both detectors within this system provide users with simultaneous chromatograms for aromatics and aliphatics, thereby eliminating the need for separate analysis procedures to be performed.
- Patented design
- Utilizes only a single GC detector port
- Tandem design allows for two simultaneous chromatograms to be acquired from a single injection
- Eliminates the need for any transfer lines between detectors
- Improved peak shape
- Better performance rates
- Utilizes GC electronics or OI Analytical’s dual channel electrometer
