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 Tube Conditioner (TC 2) enables simultaneous conditioning of up to 10 TDS tubes or up to 50 GERSTEL Twisters.
Clean and well-conditioned TD tubes and Twister are essential in order to fully take advantage of the high sensitivity of the thermal desorption technique and to achieve the best possible quality of analysis. The TC 2 operates independetly of the GC/MS system, eliminating the risk of system contamination during conditioning and keeping the GC/MS available for analytical tasks ensuring maximum productivity.
The basic platform provides 10 automated sample introduction techniques, there is no need to have a different instrument for each technique.

The LV-20 Standards Addition Module pairs with our Model 4551A Autosampler to improve accuracy and precision of GC-GC-MS analyses, while minimizing standard usage and decreasing laboratory costs of expensive standards.
Designed as an option for the 4551A Autosampler, the LV-20 Standards Addition Module injects programmed volumes (1, 2, 5, 10, or 20 µL) of internal standard, surrogate, or matrix spike standards to improve the accuracy and precision of GC-GC-MS analyses. The LV-20 is equipped with high-speed injection valves which inject user-programmed volumes of standard with no excess overfill volume that fixed-loop based systems require to operate. All LV-20 functions are programmed using the intuitive touchscreen and Windows® CE software on the Eclipse 4760 Purge-and-Trap Sample Concentrator.
The GERSTEL Olfactory Data Interpreter (ODI) enables fast and reliable evaluation of olfactory information including identification of unknown odor-active compounds. Chromatography data is typically acquired using a mass spectrometer / mass selective detector (MSD), a Flame Ionization Detector (FID) or a Sulfur Chemiluminescence Dectector (SCD) or a combination thereof. The chromatogram is loaded into the ODI software, which automatically recognizes the chromatogram data format before importing the data. In parallel, an olfactogram is imported with information provided by the user as he or she assessed odors eluting from the GC column in parallel with the detection process during the GC run. The olfactogram combines spoken comments from the sensory analyst and the registered intensities along a time axis. The „Olfactory Intensity Device“ (OID) conveniently enables the user to indicate the intensity of the olfactory impression as it transpires. Text comments are added using voice recognition software to translate spoken descriptors. The combined information is presented in the ODI-Software in a clear and concise overview including a chromatogram, an olfactogram and a table.
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.
