Operates below 275oC, and gives a typical DL of ~250PPM, with linearity to
~ for most species. A good nondestructive detector for general Organic and Analytical testing, it is also used for
Combustion 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 a
working range from ~10PPM to 10% for C1-C10 compounds. It has a high temperature range, over 400oC, and can be
interfaced with add-on detectors for selective-species measurements. Solvent and material characterization, environmental
samples, TPH and petroleum analyses are primary applications. Air & Hydrogen are support gases, using Helium for a carrier
gas.
3) DELCD (Dry Electro-Lytic Conductivity Detector) This detector, with FID, is ideal for environmental applications where
Halogenated Hydrocarbons and Pesticides can be easily differentiated from Solvent matrix backgrounds. Cleaner and more
linear response of DELCD compared to ECD still gives sensitivities in the 10PPB range; and meets most EPA specifications for
the 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 gaseous
species with an Ionization Potential below that of Helium. Less expensive than similar detectors; it provides DLs of ~1-10PPM
for most gases. Suited for special tests; such as Transformer Oil Gases, Road Bed Emissions and other non-Organic vapor
measurement. High-quality Helium is required as Carrier.
5) NPD (Nitrogen Phosphorus Detector) Designed for Agricultural and Drug testing, this modified Thermionic Bead Detector
responds to Nitrogen-bearing compounds to concentrations of ~100PPB or lower; with Phosphorus-containing materials
detectable at ~500PPB. As part of an FID assembly, it needs the Air-Hydrogen jet to burn the eluting “peak” with a Helium
carrier.
6) ECD (Electron Capture Detector) Originally designed for single PPB level detection of Chlorinated organic compounds, it
requires a special carrier gas of Argon-Methane and low-bleed columns for optimal results Still the most sensitive detector
available for the environmental monitoring of Halocarbons and Pesticides, with 1-5PPB detection limits. Usually run independent
of 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 Aromatic
compounds make it ideal for environmental testing for BTEX, PAH and PNA species. Non-destructive measurements make it
ideal 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 burning
Sulfur or / and Phosphorus compounds. Crucial for Stack and Combustion Gas testing,Natural Gas, refined Hydrocarbons and
even Pesticide materials. Superior detection limits in the 1-10PPB range are achieved with advance electronics and proprietary
optical 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 hydrocarbon
compounds has a typical detection limit of
temperatures (<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. Packages
such as FID-DELCD, TCD-FID, PID-FID- DELCD, NPD-DELCD, FID-FPD. Call for specific application help on your
application.进样器:Several injection options are available for the Buck 910/310.
Injector types and configurations are selected by the user depending on the
particular measurement application, detection limit required and regulatory
specifications. All injectors require factory installation.
On-Column Injector
The On-Column injector is supplied standard on all 910/310 GCs. This mode of injection
introduces the sample directly into the bore of the column, avoiding the possibility of boiling
point discrimination or other uncertainties. A heated injector upgrade is available.
Heated Split/Splitless
The Heated Split/Splitless injector permits the use of narrow-bore capillary columns when
needed. The injector temperature is adjustable from ambient to 300oC and the split flow is
adjustable by means of a precision needle valve. This feature can be turned on/off by using
a timed event from the PeakSimple software.
10 Port Gas Sampling Valve & Heated Valve Oven
The 10 Port Gas Sampling valve can be plumbed in many ways to perform a variety of analytical tasks, providing additional
flexibility 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 oven
consists of an insulated aluminum box mounted immediately next to the column oven. This means very little tubing is needed for
connections which results in sharper peaks. The valve oven can accomodate 2 electrically operated plus one manually operated
valve and can be thermostatted from ambient to 175oC. A heated oven is highly recommended for gas sampling valve mounting
and is required for several other options
42 Vial Liquid And 20 Vial Internal AutoSampler
The autosampler uses readily available 2ml vials with crimp or screw tops. The
autosampler flushes its syringe with the sample itself, so each vial must be filled
with at least 1ml of sample. The PeakSimple data system tells the autosampler
to flush the syringe, inject the sample and then advance the tray to the next vial
position. The autosampler can be used with the on-column, heated, or split/
splitless injectors. The 42 vial external Autosampler requires nitrogen, air or
helium at 60 psi to actuate the moving parts. The internal 20 vial Autosampler
is electronically actuated and is run from peaksimple sample queue. The
injection volume is adjustable from 0-3 μl.
Heated Static Headspace Injector
The Heated Static Headspace Injector is useful for the analysis of volatiles,
especially where the sample matrix is dirty. A standard 40ml VOA vial is
inserted into a thermostatted sleeve, where two needles puncture the septum
top of the vial. Purge gas enters through one needle to pressurize the vial and the other needle carries the headspace vapors to the
loop of the gas sampling valve or trap.
EPA Method 5030/5035 Compliant Purge & Trap
The 5030 as well as the 5035 Compliant Purge & Trap concentrate the volatile organic compounds (VOCs) in a gas, water, or soil
sample onto two adsorbent traps from which they are automatically desorbed into the GC column. The 5035 Purge & Trap is
equipped with an adjustable temperature thermostatted sleeve that accommodates a standard 40ml VOA vial containing the water
or soil/water sample. The entire sleeve is mechanically agitated during purging to comply with the requirements of EPA Method
5035.PeakSimple-软件:PeakSimple chromatography software combines quick
learning, ease of use and convenient powerful features
for GC and HPLC. PeakSimple is included in the price
of every Buck Gas Chromatograph and Data System.
PeakSimple’s intuitive graphical functions and features
are user-friendly, so most operators can produce results
almost immediately and without specific training. Yet
PeakSimple is packed with state-of-the-art features like
draggable retention time windows, seldom found in other
software packages costing much more.
PeakSimple has the ability to be used with a small
portable notebook or a full-sized computer to control
instrument functions and process data. This feature is
highly desirable for field applications. There is no
additional hardware or interfaces required.
PeakSimple even includes built-in data validation, an
extra cost on other data systems. This option allows
you to replay and load a stored chromatogram, to determine the reproducibility and precision of the entire system.
PeakSimple also includes baseline subtraction, chromatogram overlays, DDE
multi-level calibrations, autosampler queue, batch reprocessing and many other convenient features. Peaksimple

spreadsheet or word processor色谱选配件:Vacuum Pump Interface
This 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 or
to load the loop of a gas sampling valve by pulling sample gas from a remote location. Because the vacuum pump can be
turned 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 Columns
Buck can supply and install most types of columns. The metal megabore capillary
columns 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 some
applications (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 Accessory
The methanizer accessory is a high efficiency catalyst which is mounted inside the
FID and thermostatted to 380oC. The tube is packed with a special nickel catalyst
powder where CO and CO2 are converted to methane for detection by FID down to
1ppm. This methanize design must be configured with a FID detector.
Built-in Air Compressor And Hydrogen Generator
The built-in “whisper quiet” air compressor is mounted inside the chassis of the 910 GC where it provides a nearly silent
supply 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 generator
can run an FID detector for days on a single filling of water, saving even more money and space.
Gas Line Installation Kit
The 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 tubing
Stainless steel gas line filter
Handy tubing cutter
Extra Swagelok nuts and ferrules
Note- Each type of gas cylinder has a different type of CGA connection to the
regulator. Air is typically CGA 590 or 346, Helium and Nitrogen are CGA 580, while
Hydrogen and Argon-Methane are CGA 350. Please specify CGA type.
GC Maintenance Kit
The GC maintenance kit includes most parts which could fail and is designed
especially for our export customers who may have difficulty returning the GC to the
factory for service.
