The OI Analytical Tandem PID/FID detector is a combined detector system incorporating the OI 4430 PID and OI 4410 FID models.
The patented tandem design uses a single GC port and allows for the acquisition of two chromatograms simultaneously from a single injection, eliminating transfer lines between detectors and improving instrument performance and peak shape.
With the combination of these two detectors, dual detection of trace amounts of benzene, toluene, ethylbenzene and xylene is possible, eliminating the need for duplicate analyses.
Excellent results can be obtained with both capillary and packed columns.
Since the tandem detector uses only one detection channel, two 4550 models can be installed on the same GC and provide dual outputs.
