of valuable laboratory floor or bench space
High purity hydrogen, nitrogen and zero air gas at flow rates
to suit any GC configuration
Complete gas solution for carrier, detector, reference, flame
support and sample preparation
Proven and robust safety systems including internal leak
detection on hydrogen models
12 month warranty across the range, 3 year PEM cell warranty
on Hydrogen models

Precision with convenience
Precision gas generators support thousands of GC applications throughout the world providing
any combination of nitrogen, hydrogen or zero air to supply detector and/or carrier gas to
support your specific GC setup.
Through our understanding of your priorities to have safer, more efficient, high purity gas in the
lab, we have used our expertise to develop the Precision series; a total gas solution for GC and
GC-MS.
Core to the Precision Series are the Hydrogen Trace and Nitrogen Trace models, cost-effective
alternatives to helium - an increasingly expensive gas for laboratories worldwide as demand
outstrips supply.

Complete GC gas solution
• Enhance Workflow
Produce gas on demand, minimize disruptions
and run samples around the clock without any risk
of supply loss or running out of gas mid-analysis
streamlining your workflow.

• Improve Safety
Multiple integrated safety features within all models,
including internal leak detection on hydrogen
models with low stored volume and pressure of gas.
Far safer than highly pressurized cylinders.

• Future Proof
Combine different generators into a single stack to
suit your lab’s GC configuration with multiple flow
rate options to future proof your GC carrier and
detector gas supply.

• Save Space
Modular design allows for a small laboratory footprint
and if starting with one or two modules, additional
units can be stacked on top, minimizing the impact on
your lab’s floor or bench space.

Modular configurations
The Precision Series can be stacked in multiple variations depending on your lab’s particular
GC requirement, whether it is to supply GC carrier gas on its own, delivering flame support gas
to detectors or for other detectors like TCDs or ECDs.
The Precision Series can also be purchased with an optional, stackable air compressor module
for labs without a suitable air supply for the nitrogen or zero air generators.

Why switch carrier gas?
Comparison of Detailed Hydrocarbon Analysis using ASTM method D6729 & D6729 appendix X2
shows run times can be reduced by as much as 40% when switching from helium to hydrogen.
As helium costs increase and availability becomes more uncertain. A switch to hydrogen carrier
gas allows you to take control of your gas supply, reduce costs and improve efficiency.

Performance
Increase your lab’s productivity
Precision is designed and manufactured to enhance workflow for labs using GC. Removing the hassles and
inconvenience of cylinders, such as running out of gas mid-analysis, managing supply stocks and placing orders.
Replacing helium cylinders with a hydrogen generator can also bring faster run times, increasing the number of
samples your lab can run daily.

Safety as standard
Precision gas generators greatly reduce risks in the laboratory. Manual handling of highly pressurized
cylinders in the lab remains a significant potential hazard. With Precision, not only are highly pressurized
and heavy cylinders removed from the lab environment, but multiple safety features are also included as
standard such as auto-shutdown on leak detection, mechanical shutdown fail-safe, minimal volume of gas
stored and gas generated on demand.

Quality assured performance
All Peak gas generators are tested to comply with a number
of internationally recognized standards including CE &
CSA. Manufactured at Peak’s ISO 9001 accredited center of
excellence and supported on-site by Peak’s global network of
Peak field service engineers, Precision delivers a consistently
pure GC gas supply laboratories can rely on.

Peace of mind
“A key benefit for us has been the elimination of
the safety hazards associated with compressed
gas cylinder handling.”
Kerri Heckrow, Corporate NPD Lab Manager,
Evergreen Packaging, North Carolina, USA

“We have gas available on demand and we don’t have
to worry about the purity or running out. There are also
cost benefits in that we no longer have to order cylinders
and pay monthly rental.”
Brian Cowan, Laboratory Manager, Council for Scientific
and Industrial Research (CSIR), South Africa

“The Peak generators were highly recommended by
Shimadzu and were sold as a package with the GC-MS.”
Federico Cozzi, Laboratory Manager, University of
Copenhagen, Denmark
