The Model 4430 Photoionization Detector (PID) is a uniquely-designed gas chromatograph (GC) that selectively responds to aromatic and olefinic hydrocarbons in the presence of alkanes and other saturated hydrocarbons.
Our Model 4430 PID’s unique patented Window Sweep™ design prevents the sample stream from contacting and contaminating the lamp window.
Experience the convenience and flexibility of the Model 4450 Tandem Photoionization Detector/Flame Ionization Detector (PID/FID): a patented combination gas chromatography (GC) detector incorporating the Model 4430 PID and Model 4410 FlD.
The Model 5320 Electrolytic Conductivity Detector (ELCD) excels in select detection of halogen-containing compounds, while also proving its flexibility by offering sulfur and nitrogen detection.
The Model 5320 is our third-generation ELCD. It combines three key components: a reactor assembly, cell-solvent assembly, and detector controller.
Increase efficiency and save counter space with the Model 5350 Tandem Photoionization Detector/Electrolytic Conductivity Detector (PID/ELCD), a smartly designed instrument for dual detection of aromatic and halogen compounds.
The Model 5350 Tandem PID/ELCD packs in the power of two great detectors: Model 4430 PID and Model 5320 ELCD, removing the need for separate analyses of aromatic and halogen compounds.
The Model 5360 XSD™ offers superior selectivity for detection of halogen-containing compounds.
Installed in the standard port of a gas chromatograph (GC), the Model 5360 XSD™ detects halogen-containing compounds eluting from the GC’s capillary column. This instrument is unique in the fact that it doesn’t contain radioactive sources or use organic solvents like other halogen selective detectors. This eliminates the need for catalyst tubes, solvents, resin cartridges, pumps, and transfer lines.
The Model 5383 Pulsed Flame Photometric Detector (PFPD) uses superior sensitivity and increased selectivity to easily and accurately analyze sulfur, phosphorus, and 26 other elements.
The superior sensitivity of the 5383 PFPD makes it the instrument of choice for the analysis of sulfur, phosphorus, and other elements. Its linear, equimolar response to sulfur allows selective measurement of individual sulfur species from low ppb to ppm levels, and total sulfur as the sum of individual peaks. The unique capability to obtain simultaneous sulfur and hydrocarbon chromatograms from a single PFPD detector sets it apart from other sulfur detection technologies.
Work smarter with the Model 5390 Tandem PID/XSD, which combines the power of the 4430 Photoionization Detector (PID) and the 5360 Halogen Specific Detector (XSD) to simultaneously detect halogen and aromatic compounds.
This patented tandem detector offers the production of two gas chromatograph (GC) detectors, the 4430 PID and 5360 XSD, in one efficient package. Its unique design eliminates transfer lines and uses only one detector port.
The ODP sniff port allows the sensing of compounds by the human nose as they elute from the gas chromatograph. The effluent is split as it leaves the column so that it arrives simultaneously at the nose and at the detector.
This way additional information is gained on compounds that are responsible for specific odors.
The GERSTEL PFC automatically collects compounds after gas chromatographic separation. The PFC is equipped with six sample traps and one waste trap. Traps are available in 1 µl or 100 µl volumes.
For optimum compound recovery, the PFC can be equipped with optional LN2 trap cooling or cryostatic trap cooling systems.
