Super-Clean™ Gas-Trapping
System for LC/MS
New Quick-Change System Removes
Hydrocarbon Impurities from Nitrogen

The Super-Clean™ Gas-Trapping System is the latest
technology in cartridge systems for gas purification,
and is ideal for purifying nitrogen for LC/MS sys-
tems. Changing cartridges is quick and easy. A two-
position base plate, installed in the gas line, allows
you to exchange cartridges without introducing oxy-
gen into the system: spring-loaded check valves seal
when a cartridge is removed and open only when a
new cartridge has been locked in place. There is no
need for loosening and tightening fittings every time
you change cartridges, and your system cannot
become contaminated during the changing process.
To meet the high flow needs of an LC/MS system,
the two cartridges are positioned and connected in
parallel. The incoming gas stream is split equally
between the two cartridges, and the two streams
are rejoined after purification but before the gas
exits the base plate. This approach allows longer
contact between the nitrogen and the charcoal
adsorbent, ensuring higher gas purity. The system
can deliver up to 20L of 99.9999% pure nitrogen
per minute, at a maximum pressure of 11 bar
(160psi). Estimated cartridge lifetime is 3 to 6
months.

A Wealth of Practical
Chromatography
Experience, at a
Location Near You
Again this year the chromatography wizards from
Restek are presenting comprehensive
seminars designed to help you minimize down-
time and obtain the results you want. We keep
these seminars to one day, and hold them at sites
all around the country, to minimize the time you
spend away from your lab and conserve your
travel budget. The low cost of the seminar is an
investment that can be quickly returned, because
you will improve your lab throughput and spend
less time dealing with problems. Choose the topic
that suits your work:
Comprehensive Capillary GC
Environmental GC Analysis
Comprehensive HPLC
Food, Flavor, and Fragrance Analysis
Our brochure 2002 Seminars (lit. cat.# 59282A)
provides details about these seminars and lists
dates and locations. Call, fax, or e-mail your
request for the seminars brochure today, or view it
on our website. We look forward to meeting you.
