Tandem PID/XSD

Unique tandem design eliminates need for transfer lines and minimizes dead volume.
Patented tandem detector design uses only one GC detector port
Exclusive Lampsaver™ circuit turns PID lamp off (if desired) after a specified period when not in use, to extend lamp life.
High sensitivity with selective detection of halogenated compounds.
Low maintenance and increased stability and reliability.
Unique jet design minimizes peak tailing due to unswept dead volumes or transfer lines.

The Model 5390 Tandem PID/XSD is a patented tandem detector configuration incorporating the popular 4430 Photoionization Detector (PID) and the 5360 Halogen Specific Detector (XSD™). With the detectors in tandem, simultaneous detection of halogen and aromatic compounds is possible, eliminating the need for two separate analyses. Its unique design eliminates transfer lines and uses only one detector port. Both detectors can be used independently, if desired. The XSD’s simplified design improves reliability and performance, and reduces costs. The XSD is also a more selective alternative to an ECD.
