The Super-Clean™ Gas Trapping System is the lat-
est technology in cartridge-style gas filtration for
removing hydrocarbons from nitrogen, and is
ideal for use in LC/MS systems. The cartridge-
based system makes changing filters quick and
easy. A two-position baseplate (1 /4" fittings),
installed in the gas line, allows cartridges to be
exchanged without introducing oxygen 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 chang-
ing process.

Super-Clean™ Gas Trapping System for LC/MS
Quick-Change Cartridge System for Removing Hydrocarbon Impurities
from Nitrogen
by Donna Lidgett, Purus™ Gas Systems Product Marketing Manager
• “Quick connect” fittings, for easy, leak-tight cartridge changes—no tools required to
install the traps.
•Spring-loaded check valves—no loosening/tightening fittings each time you change a cartridge.
•No oxygen introduced during filter change-outs—decreases down time.
•Cartridges pre-purged with inert gas—saves time.
•Durable, patented full glass/metal design—combines safety and impermeability.
To meet the high flow needs of the LC/MS sys-
tem, the incoming gas stream is split equally
between the two charcoal-filled 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 adsorbent, ensuring higher gas
purity and eliminating a potential source of con-
taminants to your analyses. The system delivers
flows of up to 20L of hydrocarbon-free nitrogen
per minute.
A handy date wheel, included with the system,
indicates the cartridge installation date and the
recommended replacement date.
