Super-Clean™ system: fast, simple cartridge
changes
Cartridge-style gas purification systems make chang-
ing gas filters quick and easy, and the Super-Clean™
gas filter system is the latest improvement to car-
tridge-style technology. A baseplate in the Super-
Clean™ system allows cartridges to be exchanged
without introducing atmospheric oxygen and water
vapor: spring-loaded check valves seal when a car-
tridge is removed and open only when a new car-
t oo l s
tridge has been locked in place. You no longer need
to loosen and tighten fittings every time you change a
cartridge, and your system cannot become contami-
nated during the changing process.
Use a 2- or 3-position baseplate to purify multiple
GC gas streams at one location—Figure 1 shows
some possible filter cartridge combinations. Many
combinations are possible because any Super-Clean ™
filter cartridge can be used with any baseplate.
Super-Clean™ Gas Filters
High-purity output improves sensitivity
The Triple Filter cartridge (cat.# 22020) is ideal for
purifying carrier gas (Figure 1). It combines oxygen,
moisture, and hydrocarbon removers in one car-
tridge. Purity of carrier gas leaving a Triple Filter is
better than “six nines” (99.9999%), which is ideal
for noise-free baselines from sensitive mass spec-
trometry or electron capture detection equipment,
and for protecting your analytical columns against
damage from contaminants.
The Fuel Gas Filter cartridge (cat.# 22022) is perfect
for purifying flame ionization detector fuel gases,
removing both moisture and hydrocarbons. Use Fuel
Gas Filters in a 2-position baseplate for FID hydro-
gen and air (Figure 1), to produce a stable baseline
and improve overall sensitivity and reproducibility.
The new Helium Specific Carrier Gas Cleaning Kit
(cat.# 21983) is designed specifically for purifying
helium used in GC/MS systems. The cartridge is pre-
pared and conditioned using high-purity helium, to
minimize conditioning time in your system.
All Super-Clean™ filter cartridges except the
hydrocarbon cartridge feature
easy-to-read indicators.
The indicator code is shown on every trap
so there is no confusion about when to
replace it.
