ChromGas Hydrogen &
N2 LC/MS Generators
The Best Value in Laboratory Gas Generators
✔ No high-pressure cylinders means improved lab safety.
✔ Ultra-high purity for better chromatography.
by Gary Barone, GC Accessories Product Marketing Manager
Restek has developed a marketing alliance with
Parker Hannifin Corporation, Filtration and
Separation Division—formerly Whatman—to offer
gas generators world-wide. Parker Hannifin now
provides the best value in laboratory gas generators.
The ChromGas fuel-grade hydrogen generator is a
hazard-free alternative to high-pressure gas cylin-
ders. The ChromGas generators use an exclusive
solid polymer electrolyte to produce hydrogen on
demand. Deionized water and an electrical supply
is all that is needed to generate hydrogen for weeks
of continuous operation.
With an output capacity up to 500cc/min., this gen-
erator can supply 99.9995% pure hydrogen to over
ten gas chromatographs (GCs). Based on cylinder
gas savings alone, a ChromGas hydrogen generator
pays for itself in less than a year.
The Parker ChromGas hydrogen generators are cer-
tified for laboratory use by Canadian Standards
Association (CSA), Underwriters Laboratories (UL),
and International Electrotechnical Commission
(IEC) 1010. A built-in sensing circuit shuts the gen-
erator down if a hydrogen leak is detected.
Nitrogen Generator and Air Compressor All
in One—Ideal for LC/MS!
The Parker N2-15 generator incorporates an oilless
air compressor and membrane nitrogen generator
assembled as a package specifically to feed LC/MS
systems. The N2-15 produces 15 liters-per-minute
at 99% purity. The N2-15 generator is an ideal,
safe, and less expensive long-term alternative than
nitrogen cylinders or bulky dewars.
The N2-15 generator is a convenient, inexpensive
solution to high-volume nitrogen generation.
Previously a compressor and generator would have
to be purchased separately. Often the end-users
were responsible for installing and interfacing the
compressor and generator. The cost of a reason-
able system was well in excess of $20,000. Now the
N2-15 generator solves the installation and set-up
difficulties at a very attractive price.
