Widely used in laboratory and process gas chromatographs to analyze sulfur species and total sulfur levels in liquid-phase petrochemicals, you will also find the Model 5383 hard at work analyzing organophosphorus pesticides, pharmaceuticals, flavor and fragrances, beverage-grade CO2, chemical warfare agents, and more.

Model 5383 PFPD Features

• Linear, equimolar response for quick, easy calibrations
• Simultaneous mutually selective chromatograms (e.g., S+C, or S+P)
• Self-cleaning design eliminates soot formation, or “coking”
• New, modular design with separate electronics and flow modules
• Better long-term stability and less maintenance than other S-selective detectors, such as SCD/XRF – Uses less gas than SCDs

The 5360A XSD option offers a heated base assembly which provides improved baseline stability and easy column installation. Both the 5360 and 5360A models can be installed as stand-alone detectors or used in tandem with the Model 4430 Photoionization Detector (PID).

XSD Features:

• High halogen selectivity vs. hydrocarbon simplifies analyses and minimizes (or eliminates) the need for sample preparation
• High detector sensitivity permits very low-level selective analysis of halogen-containing (Cl, Br, F) compounds
• Unique jet design minimizes peak tailing due to unswept dead volumes
• Requires only air to operate
• Designed to operate on most GC makes and models
• No routine maintenance required
• Enhanced venting option diverts solvent before entry to the reactor

Its principal mode of operation is the halogen mode (X), but sulfur (S) and nitrogen (N) modes are also available. Each detection mode kit contains all of the required materials (except the solvent) to operate the ELCD in specified mode.

ELCD Features:

• Quick-change reactor design, disposable resin cartridge, and reliable solvent system
• Analog-controlled reactor temperature and solvent flow
• Detector base optimized for capillary columns
• Solvent venting using GC timed-event relay
• Direct interface with most GC makes and models
• Direct interface to the OI Analytical Model 4430 PID without a transfer line; tandem design occupies only one detector port

It also allows analysis of photosensitive compounds, which would otherwise combine to form a polymer on the window surface.

PID Features:

• UV-lamp Window Sweep design minimizes fouling from window surface contamination
• Lampsaver circuit extends lamp lifetime by turning off when not in use
• Direct interface to ELCD, XSD, or FID to form tandem detector systems; requires only one detector port
• Detector vent for venting undesirable sample solvents
• Compatible with packed and capillary columns
• Custom engineered to fit specific GC models
• Easy operation and maintenance

Its unique design eliminates transfer lines and uses only one detector port. Detectors can be used separately if desired. The 5350 Tandem PID/ELCD is compatible with most GC manufacturer’s instruments.

Model 5350 Tandem PID/ELCD Features:

• Unique tandem design eliminates transfer lines and minimizes dead volume
• Tandem detector design uses only one GC detector port
• Patented UV Lamp Window Sweep design minimizes fouling from window surface contamination
• Exclusive Lampsaver circuit can be programmed to turn PID lamp off after a specified period to improve lamp life
• ELCD incorporates quick change, disposable deionizing resin cartridge, and a simplified solvent system
• Reactor design uses brass and graphite/Vespel® ferrules instead of solid graphite ferrules
• Programmable solvent venting through GC timed event

Our dynamic duo Model 4450 Tandem PID/FID offers the goodness of two detectors packed into one convenient instrument. Together, the detectors produce simultaneous chromatograms for aromatics and aliphatics, eliminating the need for separate analysis.

Tandem PID/FID Features:

• Patented design uses only one GC detector port
• Tandem design acquires two simultaneous chromatograms from a single injection
• Elimination of transfer lines between detectors improves peak shape and performance
• System uses GC electronics or OI Analytical’s dual channel electrometer

The model 5390’s simplified design improves reliability and performance, and reduces costs. Detectors can be used individually if desired.

5390 Tandem PID/XSD Features:

• Unique design eliminates need for transfer lines and minimizes dead volume
• Patented tandem detector design uses only one GC detector port
• Exclusive Lampsaver circuit can be programmed to turn off PID lamp after a specified period 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 GERSTEL PFC allows for the collection of individual compounds, a series of compounds, or specific classes of compounds. Thanks to microprocessor control, trap switching times can be selected to within 0.01 minutes. This permits reliable collection of individual compounds that are closely resolved.

The PFC is designed without valves or cold spots in the sample flow path ensuring maximum transfer efficiency.

The reliability and reproducibility of the system makes it possible to trap compounds over hundreds of injections. This makes it possible to further analyse the fractions by techniques requiring larger sample mass such as NMR or IR.

The system can be controlled through the MAESTRO software.

Main Features and Advantages

• Automated collection of compounds or compound groups
• Six collection traps using cryo-trapping or adsorbent
• Purification of compounds from 100s of runs
• Separate waste trap (can be cooled for residue collection)
• No valves and no cold spots for best possible recovery
• MAESTRO Software control for easy set-up

The GERSTEL PFC can be used with all standard gas chromatographs.

GERSTEL ODP offers:

• Parallel operation with most standard detectors, including MSD
• Humidifier for convenient usage
• Voice recording and voice recognition: Spoken comments are transferred and added automatically to the chromatogram as peak annotations
• ODP 3 provides a heated mixing chamber in which humidified make-up gas and column effluent are mixed without risk of condensation

NEW: Olfactory Data Interpreter (ODI) Software

The Olfactory Data Interpreter (ODI) software enables time-aligned sensory evaluation of compounds eluting from the GC/MS complete with intensity levels and qualifiers displayed in a combined olfactogram. Compounds can be searched in the NIST database and their identity added and reported.

The ODI software provides the analyst with helpful software tools that are also relevant for evaluation of sensory panel data such as: Cumulative Olfactogram presentation, Aroma Extract Dilution Analysis (AEDA), Flavor Dilution (FD), as well as Multivariate Data Analysis (PCA).
