GC with FID and TCD from Buck Scientific: 910 GC with FID & TCD
detectors 30 Meter column, and built-in air compressor
In the lab, the 910-series GCs perform routine industrial analyses
and complicated research separations easily, generating accurate and
reproducible results. Designed to be durable and portable, the compact
310-series is ideal for operation in the field, E.P.A. and A.S.T.M.
methods can be easily performed on-site, even in adverse field
environments. Use the 910 & 310 and obtain quality results.
A GC with the versatility to meet your lab’s specific needs. The
unique architecture of the Buck GC systems allow various detector and
injector combinations, so each GC can be configured to meet your
specific lab requirements. The full-size 910-GC can accommodate multiple
injectors and detectors for multi-functional applications, while the
smaller 310-GC is equally flexible for portable and field analysis.
Let the GC do the work so you don’t have to -The Buck 910/310 offer
total control of applicationparameters using PeakSimple software.
PeakSimple allows unlimitedtemperature programming, electronic pressure
control, carrier gas pressure,gas valve position, gas solenoid
actuation, autosampler control and other options. Just program your
application parameters into the computer and let the 910 do the rest.
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.
- Universal detector
- Detects from 100% down to 200-500 ppm
- Easily replaceable filaments
- Thermostatted up to 275° C
Because it detects all molecules, the Thermal Conductivity Detector is
commonly used for fixed gas analysis (O2, N2, CO, CO2, H2S, NO, etc.)
where the target analytes do not respond well on other, more sensitive
detectors. The TCD can detect concentrations from 100% down to around
100 ppm on a flat baseline with sharp peaks. Where the peak is broad or
the baseline is not flat, detection limits of 300 ppm are more
For lower detection limits, the HID detector may be more suitable
for inorganics, and the FID detector provides 1ppm detection for
The TCD consists of four tungsten-rhenium filaments in a Wheatstone
bridge configuration. Electric current flows through the
filaments, causing them to heat up. Carrier gas (usually helium, which
has very high thermal conductivity) flows across the filaments,
removing heat at a constant rate. Two of the filaments are exposed only
to carrier gas (reference), and two are exposed to the carrier/sample
flow. When a sample molecule with lower thermal conductivity than the
carrier gas exits the column and flows across the two sample filaments,
the temperature of the filaments increases. This temperature increase
unbalances the Wheatstone bridge and generates a peak as sample
molecules transit through the detector.
A filament protection circuit prevents filament damage by disabling
the current if carrier pressure is not detected by the GC, but cannot
prevent filament damage in all circumstances. The TCD is equipped with
user-replaceable filaments in the event of a burn-out.
