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. Automated Analyses

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.

TCD Detector

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 realistic.
For lower detection limits, the HID detector may be more suitable for inorganics,
and the FID detector provides 1ppm detection for hydrocarbon species.

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.
