Super-Clean™GasFilters
• High-purityoutput ensures 99.9999%pure gas.
• “Quick connect”fittings for easy, leak-tight cartridge changes.
• Glass inside toprevent diffusion; plastic outside for safety.
Designed for fast, simplecartridgechanging
Cartridge systemsmake changing gas filters quick and easy, andSuper-Clean™ gas filters are the latest in
cartridge-style gas filtration.A baseplate allows cartridges to be exchangedwithout introducing oxygen.
Spring-loaded checkvalves sealwhena filter is removedandopenonlywhenanew filterhasbeen locked
inplace.There is no longer aneed for loosening and tightening fittings every time a trap is changed, and
your systemwill not become contaminatedduring the process.
With available 2- or 3-position baseplates, you can purify all GC gas streams at one location. Figure 1
shows some possible filter cartridge combinations using these baseplates. Any combination is possible
because anyRestek Super-Clean™ filter cartridge canbeusedwith anyRestekbaseplate.
High-purityoutput for improvedsensitivity (Table I)
TheTripleFilter cartridge (cat.#22020) is ideal forpurifyingcarriergas.This trapcontainsoxygen,mois-
ture,andhydrocarbon scrubbers inonecartridge.Thepurityof your carriergasafter flowing through the
TripleFilter is better than six-9s (99.9999%pure),which is ideal for sensitivemass spectrometry (MS) or
ECDanalyses, and forprotectingyour analytical columns against damage from contaminated carrier gas.
The Fuel Gas Filter cartridge (cat.# 22022) is perfect for purifying flame ionization detector (FID) fuel
gases, removingbothmoistureandhydrocarbons.Using theFuelGasFilter forFIDhydrogenandairwill
produce a stable baseline, improvingoverall reproducibility and sensitivity.

Oxygen andMoisture Traps
We highly recommend
oxygen andmoisture traps for
make-up gaswhen operating
sensitive detectors such as
electron capture detectors
(ECD).The hydrogen reaction
gas for sensitive electrolytic
conductivity detectors (ELCD)
also requires a hydrocarbon
trap, to remove trace
impurities.
