Making Gas Connections
To prepare for the gas connections:
• Remove any 1/16-inch or 1/8-inch VICI plugs and 1/4-inch VCR caps from
the ta7000F Rear Panel.
• Remove all other shipping caps immediately prior to connection of gas sup-
plies.
• Refer to Figure 2-3 for gas connection port locations.
Connecting the Sample and Carrier Gas
The ta7000F Monitor for
inerts
(Ar, He, N
2
) uses purified sample gas as a chro-
matographic carrier. Matching the carrier gas to the sample gas will prevent
upsets caused by the elution of the extraneous balance peak. The instrument
connection is made at the Carrier/Sample Inlet 1/4-inch male VCR port on the
ta7000F Rear Panel.
The ta7000F Monitor for
reactives
(O
2
, H
2
) uses purified nitrogen gas as a
chromatographic carrier. This instrument connection is made at the Carrier/
Sample Inlet 1/4-inch male VCR port on the ta7000F Rear Panel. The Sample
gas connection is then made at the Sample Inlet 1/4-inch male VCR port on the
ta7000F Rear Panel. Pressurize the external line to 80 PSIG (minimum 70 PSIG,
maximum 90 PSIG).
