Selective Detectors for Gas Chromatography

Open the catalog to page 1

Enhancing Chromatographic While gas chromatography coupled with mass spectrometry (GC-MS) is a powerful analytical technique, there are significant advantages to using selective GC detectors alone or in tandem with a MS detector for many applications. A mass spectrometer is a universal, nonselective detector that yields total ion chromatograms containing a large number of compounds. Post-run mass spectra library searching is required to identify target compounds. Selective GC detectors enhance chromatographic performance by measuring trace levels of target compounds in the presence of...

Selective Detectors for Gas Chromatography - 3

Performance Selective GC Detectors for Challenging Analytical Applications OI Analytical’s selective GC detectors provide solutions to challenging analytical applications. Detecting sulfur species in petrochemicals, trace levels of organochlorine and organophosphorus pesticides in food samples, or sulfur and aromatic compounds in flavor and fragrance extracts are prime examples of applications that benefit from the use of selective GC detectors. Compatible detectors are available for current models of GC instruments manufactured by Agilent, Bruker, Shimadzu, Thermo, and PerkinElmer. Sulfur...

Selective Detectors for Gas Chromatography - 4

Selective GC Detectors PFPD – Pulsed Flame Photometric Detector The PFPD excels at selective detection of sulfur and phosphorus compounds, and can be configured to detect 26 other elements. XSDTM – Halogen Specific Detector The XSD halogen specific detector is designed for selective detection of halogenated compounds such as pesticides, THMs, and PCBs. OI Analytical’s patented* tandem GC detectors combine a photoionization detector (PID) with an FID or second selective detector providing two simultaneous chromatograms from a single run. The PID selectively responds to aromatic and...
