Gas supply
- External gas supply
Gas bottle provided with a proper working two-stage pressure assembly to adjust the carrier
gas pressure to 550 ± 10 kPa (80 ± 2psi).
- Internal gas supply
In order to fill the built-in carrier gas supply tank, a separate gas bottle must be present
having a pressure amply over 12000 kPa (120 bar, 1800 Psi).
- Purity of applied gases
Gases in gas bottles must have a minimum purity of 99.995%
- Safety regards
Gas bottles must be fixed to a table or to a wall.
Gas samples
- Never provide liquid samples to be handled!
- Type of samples: non-condensing gas
- Samples other than non-condensing gases (wet, vapors, particles and polymers) must be
filtered in advance
- Sample condition: non-condensing gas 0°C to 110°C.
- Sample pressure between 0 and 100 kPa
- Outlet of sample container must fit a stainless steel capillary of 1/16" outside diameter,
provided with a Swagelok ® female nut.
Carrier gas connection
The carrier gas line is connected from the bulk carrier gas tank to the Micro-GC on the rear
panel CARRIER IN port. You are strongly advised not to use any plastic tubing. Use only
properly rinsed copper or stainless steel tubing.
CP-Gas Clean filters are filled with nitrogen. If you are not using nitrogen as the carrier
gas, flush filters and gas lines after installation of a new filter.
Possible carrier gas combinations:
Helium (He), Hydrogen (H2), Argon (Ar) and Nitrogen (N2)
If you are using Hydrogen as carrier gas, pay particular attention to possible leaks at
connections inside and outside the CP-4900 Micro-GC (use electronic Leak Tester)

Sample gas
The CP-4900 Micro-GC is an analyzer built for the analysis of gases and vapors only. You
are advised to prepare a standard sample for routine check up of the instrument. The sample
pressure should be between 0-100 kPa, the temperature between 0 and 110 °C and it must
be filtered, preferably through a 5 µm filter. Varian, Inc. ALWAYS recommends the use of the
external filter kit Part number: CP736729.
Whenever possible remove moisture from samples offered to the CP-4900 Micro-GC.
Long storage procedure
Follow the procedure below if your Micro-GC has been stored for a long period!
• Put carrier gas on the Micro-GC
• Switch the Micro-GC ON
• Switch the TCD filament(s) OFF (in CP-Maître Elite)
• Set the column(s) temperature to the maximum (110°C or 160 °C or 180 °C depending
on the column module)
• Condition the column module, preferably overnight. This will ensure you that all the
water has been removed from the column module and no damage will occur to the TCD
filaments
