Operates below 275oC, and gives a typical DL of ~250PPM, with linearity to~100% for most species. A good nondestructive detector for general Organic and Analytical testing, it is also used forCombustion Gas and Stack Gas testing, Atmospheric monitoring, and bulk measurements. Helium is the recommended carrier.2) FID (Flame Ionization Detector) Commonly used for Organic analyses, it is specific for Hydrocarbon species with aworking range from ~10PPM to 10% for C1-C10 compounds. It has a high temperature range, over 400oC, and can beinterfaced with add-on detectors for selective-species measurements. Solvent and material characterization, environmentalsamples, TPH and petroleum analyses are primary applications. Air & Hydrogen are support gases, using Helium for a carriergas.3) DELCD (Dry Electro-Lytic Conductivity Detector) This detector, with FID, is ideal for environmental applications whereHalogenated Hydrocarbons and Pesticides can be easily differentiated from Solvent matrix backgrounds. Cleaner and morelinear response of DELCD compared to ECD still gives sensitivities in the 10PPB range; and meets most EPA specifications forthe 600- and 8000-series methods. Works best using Helium for a carrier, with Air & Hydrogen as supplemental gases.4) HID (Helium Ionization Detector) Provides “universal” detection; and is non-destructive, similar to TCD; for gaseousspecies with an Ionization Potential below that of Helium. Less expensive than similar detectors; it provides DLs of ~1-10PPMfor most gases. Suited for special tests; such as Transformer Oil Gases, Road Bed Emissions and other non-Organic vapormeasurement. High-quality Helium is required as Carrier.5) NPD (Nitrogen Phosphorus Detector) Designed for Agricultural and Drug testing, this modified Thermionic Bead Detectorresponds to Nitrogen-bearing compounds to concentrations of ~100PPB or lower; with Phosphorus-containing materialsdetectable at ~500PPB. As part of an FID assembly, it needs the Air-Hydrogen jet to burn the eluting “peak” with a Heliumcarrier.6) ECD (Electron Capture Detector) Originally designed for single PPB level detection of Chlorinated organic compounds, itrequires a special carrier gas of Argon-Methane and low-bleed columns for optimal results Still the most sensitive detectoravailable for the environmental monitoring of Halocarbons and Pesticides, with 1-5PPB detection limits. Usually run independentof other detectors.7) PID (Photo-Ionization Detector) A high-intensity “UV” source, the 10.6eV Krypton Lamp generates powerful energy to“excite” UNSATURATED organic; such as Aromatics, Olefins, Ketones and Esters. The low 10-50PPB DLs for the Aromaticcompounds make it ideal for environmental testing for BTEX, PAH and PNA species. Non-destructive measurements make itideal for use with an FID/combo detector.8) FPD (Flame Photometric Detector) Employs either a single- or double-phototube detector that “sees” the light from burningSulfur or / and Phosphorus compounds. Crucial for Stack and Combustion Gas testing,Natural Gas, refined Hydrocarbons andeven Pesticide materials. Superior detection limits in the 1-10PPB range are achieved with advance electronics and proprietaryoptical designs. Uses a rich Hydrogen flame, often used in conjunction with FID and with a Helium carrier gas.9) CCD (Catalytic Combustion Detector) A unique and economical alternative to the FID for the detection of hydrocarboncompounds has a typical detection limit of about 500 ppm when run with a helium carrier. The CCD can also run at lowertemperatures (<200°) when run on air to make a truly self contained GC.Note: Many of these detectors can be, and often should be combined to maximize the usefullnes of the Buck GC. Packagessuch as FID-DELCD, TCD-FID, PID-FID- DELCD, NPD-DELCD, FID-FPD.

All injectors require factory installation.On-Column InjectorThe On-Column injector is supplied standard on all 910/310 GCs. This mode of injectionintroduces the sample directly into the bore of the column, avoiding the possibility of boilingpoint discrimination or other uncertainties. A heated injector upgrade is available.Heated Split/SplitlessThe Heated Split/Splitless injector permits the use of narrow-bore capillary columns whenneeded. The injector temperature is adjustable from ambient to 300oC and the split flow isadjustable by means of a precision needle valve. This feature can be turned on/off by usinga timed event from the PeakSimple software.10 Port Gas Sampling Valve & Heated Valve OvenThe 10 Port Gas Sampling valve can be plumbed in many ways to perform a variety of analytical tasks, providing additionalflexibility to the 910. Because the valve oven is immediately next to the column oven, tubing runs are short with no cold spots,which results in sharper peaks. Buck offers many plumbing configurations for optimized gas analyses. The heated valve ovenconsists of an insulated aluminum box mounted immediately next to the column oven. This means very little tubing is needed forconnections which results in sharper peaks. The valve oven can accomodate 2 electrically operated plus one manually operatedvalve and can be thermostatted from ambient to 175oC. A heated oven is highly recommended for gas sampling valve mountingand is required for several other options42 Vial Liquid And 20 Vial Internal AutoSamplerThe autosampler uses readily available 2ml vials with crimp or screw tops. Theautosampler flushes its syringe with the sample itself, so each vial must be filledwith at least 1ml of sample. The PeakSimple data system tells the autosamplerto flush the syringe, inject the sample and then advance the tray to the next vialposition. The autosampler can be used with the on-column, heated, or split/splitless injectors. The 42 vial external Autosampler requires nitrogen, air orhelium at 60 psi to actuate the moving parts. The internal 20 vial Autosampleris electronically actuated and is run from peaksimple sample queue. Theinjection volume is adjustable from 0-3 μl.Heated Static Headspace InjectorThe Heated Static Headspace Injector is useful for the analysis of volatiles,especially where the sample matrix is dirty. A standard 40ml VOA vial isinserted into a thermostatted sleeve, where two needles puncture the septumtop of the vial. Purge gas enters through one needle to pressurize the vial and the other needle carries the headspace vapors to theloop of the gas sampling valve or trap.EPA Method 5030/5035 Compliant Purge & TrapThe 5030 as well as the 5035 Compliant Purge & Trap concentrate the volatile organic compounds (VOCs) in a gas, water, or soilsample onto two adsorbent traps from which they are automatically desorbed into the GC column. The 5035 Purge & Trap isequipped with an adjustable temperature thermostatted sleeve that accommodates a standard 40ml VOA vial containing the wateror soil/water sample. The entire sleeve is mechanically agitated during purging to comply with the requirements of EPA Method5035.   PeakSimple-软件: PeakSimple chromatography software combines quicklearning, ease of use and convenient powerful featuresfor GC and HPLC.

Dynamic Data Exchange (DDE)Link PeakSimple results to your DDE compatiblespreadsheet or word processor   色谱选配件: Vacuum Pump InterfaceThis interface will allow control of an external vacuum pump by turning the power on and off on a built-in power outlet.Typically a vacuum pump is used to draw gaseous samples through the traps for ambient air monitoring applications orto load the loop of a gas sampling valve by pulling sample gas from a remote location. Because the vacuum pump can beturned on for a precise length of time, the gas flow through the trap is very reproducible and will vary with pump rate.Packed and Capillary ColumnsBuck can supply and install most types of columns. The metal megabore capillarycolumns are preferred because they are durable, can be coiled to a smaller diameter,yet cost and work the same as fused silica columns, which tend to break. For someapplications (gases, freons, water, etc.) 1/8” packed columns are preferred. However,since every application is unique, consult a column manufacturer(Restek, Supelco,etc.) before selecting a column to purchase with your GC.Methanizer AccessoryThe methanizer accessory is a high efficiency catalyst which is mounted inside theFID and thermostatted to 380oC. The tube is packed with a special nickel catalystpowder where CO and CO2 are converted to methane for detection by FID down to1ppm. This methanize design must be configured with a FID detector.Built-in Air Compressor And Hydrogen GeneratorThe built-in “whisper quiet” air compressor is mounted inside the chassis of the 910 GC where it provides a nearly silentsupply of air for the FID or FID/DELCD detector flame. With the built-in air compressor, no air cylinder is required,simplifying field operations and saving the expense of replacing air cylinders on a regular basis. The hydrogen generatorcan run an FID detector for days on a single filling of water, saving even more money and space.Gas Line Installation KitThe Gas line installation kit includes everything you need to connect a single gas cylinder to the 910 GC.Each kit contains:Cylinder pressure regulator (0-100 PSI output)50’ length of 1/8” copper tubingStainless steel gas line filterHandy tubing cutterExtra Swagelok nuts and ferrulesNote- Each type of gas cylinder has a different type of CGA connection to theregulator. Air is typically CGA 590 or 346, Helium and Nitrogen are CGA 580, whileHydrogen and Argon-Methane are CGA 350. Please specify CGA type.GC Maintenance KitThe GC maintenance kit includes most parts which could fail and is designedespecially for our export customers who may have difficulty returning the GC to thefactory for service.Pre-Configured SystemsBuck offers an assortment of popular pre-configured systems for specific applications:Educational GC TCD Multiple Gas GC PCB AnalyzerMultiple Gas GC w/ Sulphur BTEX GC Enviromental GCTO-14 Indoor Air GC Gas-less Educational GC Educational GC FID
