1. Installation of a
Click-On Connector
A Click-On connector is available for gas line tubing with OD of 1/4" and
1
/8". These instructions are valid for each dimension of tubing; Restek
advises the use of stainless steel or copper tubing for gas lines, preferably.
1. Shut o the incoming gas.
2. If no trap was previously in use, cut the gas line using an appropriate
metal tubing cutter.
3. Disconnect the gas line from the analytical instrument.
4. Turn the carrier gas on and ush the gas line for 2 min with pure carrier gas; advised pressure: 90 psi.
5. Remove the blue closing plugs at both ends of the trap and connect
the Click-On connectors tightly to both ends of the gas line.
6. For stainless steel tubing, always use stainless steel Click-On
connectors; for copper tubing, always use brass Click-On connectors.
7. Flush the incoming gas line and connectors for 10 min with pure
carrier gas by pushing back the needle valve on the Click-On connector.
NOTE: SHARP EDGE!! Advised pressure: 90 psi.
8. Attach Click-On Trap to both Click-On connectors by punching the
internal membranes in the traps and tightening the knurled ring
clockwise.
9. Install outlet connector rst; then install inlet connector.
10. Flush the trap/whole system for at least 15 min with pure carrier gas;
advised pressure: 90 psi (except for He-specic traps; they are already
conditioned and need no ush). Do NOT connect the gas line to the
analytical instrument yet!
11. Once the purier has been ushed, mount the outgoing carrier gas
line to the analytical system and you are ready to go: normally, the
user should not see any notable argon or nitrogen peaks in the
chromatogram.
12. Check whole system for leaks after installation!
2. Replacement of a Saturated
Click-On Purifier
1. A purier cartridge needs to be exchanged when the visual indicators
(if applicable) start changing color. The original indicator color and
the color after saturation are printed on the front of the purier.
2. For metal traps without an indicator, it is strongly recommended you
replace the trap once a year.
3. Before installation of a new replacement trap, make sure that the
temperature of the replacement trap is more or less identical to the
temperature of the (already installed) Click-On connectors on your
gas line to avoid any leakage in connections. If the temperature is not
identical, use at least one hour of stabilization time in the same room
as the connectors.
NOTE: the data given in the table strongly depend on the level of gas
purity prior to entering the purifier.
Replacement of a metal purifier cartridge without an indicator is
recommended once a year.

Click-On Connectors
Click-On Inline Super Clean® puriers are suited for the purication of
noncorrosive gases with low contamination concentrations to a better
as 6.0 grade (99.99990%) purity. Click-On Inline Super Clean® puriers
are connected to an appropriate genuine Click-On connector, which can
only be connected to the gas line once.
CAUTION
• The maximum concentration of oxygen allowed in the gas before
entering the indicating trap is 0.5%. (Valid only for each purier
packed with O2-adsorbents and O2-indicator.)
• Maximum gas-maximum system pressure must not exceed
11 bar (160 psi).
• Install outlet connector rst; then install inlet connector.
• Do not install a purier system near or in a hot area
(i.e., the hot-air exhaust at the rear of the GC).
• Never recondition any trap, ever: for eventual recycling, please
contact your local supplier.
• Always install traps in the appropriate position with the label at
the front.
• Installation of the connector to the gas line should be done by
experienced and/or certied personnel.
• Do not forget to perform a reliable leak test, especially
when installing an indicating trap.
• During installation of a new Click-On Inline Super Clean®
indicating purier, torsion on the plastic outer protection tube
should be avoided at any time; watch out for cracks in the inside
glass tube after installation (valid only for glass Click-On types
of traps).
• The screws on the outside trap housing on both sides should
never be removed; in case these screws should be missing, the
cartridge should not be installed; it should be returned to
the supplier.
• Click-On connectors are available as spare parts
– do NOT repair damaged connectors; replace them
with new ones.
• Only use original parts to avoid malperformance and loss
of warranty.
NEVER INSTALL AN OXYGEN PURIFIER IN A GAS LINE FOR AIR:
it will result in instant saturation!
NOTE:
• Once the purier is positioned to the Click-On connector, the
PTFE seals inside the purier will be punctured, and it is necessary
to keep the trap in position by hand to prevent air entering
the system.
• After installing the trap to the Click-On connector, highly pure gas
will automatically stream from the purier into the analytical system.
• Regularly check both the big and small Viton O-rings on the
Click-On connector for hair cracks. The slightest leak may allow
moisture, oxygen, and hydrocarbons to enter the system and
contaminate the system. Also, check the glass indicating purier
cartridge for cracks with a leak detector.
• Indicator color change with moisture adsorbents devices
according to EC Directive December 1998.
• All puriers are packed under argon, except for the special,
He-specic GC-MS lter.
• As long as there is no trap connected, the special Click-On
connector will automatically block the gas stream.
NO GAS WILL PASS THROUGH THE GAS LINE!
