Site Preparation

Proper site preparation prior to installing Micro GC Fusion is very important.
Contact INFICON (www.inficon.com) with any questions regarding site preparation.

NOTE: Checkboxes () identify hardware and actions that must be addressed when

installing Micro GC Fusion.

List of Required Tools

 1 1/8" wrench recommended, or adjustable large wrench

(for attaching regulator to gas tank)

 Te fl on

NOTE: The following tools are included in the optional Install Kit (PN 952-021-G1).

 Open-ended wrench, 1/4 in. and 5/16 in.

 Open-ended wrench, 7/16 in. and 9/16 in.

®

tape for regulator connections

PN 074-615-P1A

Carrier Gas

 Open-ended wrench, 3/8 in. and 7/16 in.

 Hex driver, 2.5 mm ball-point long shank

 Tubing cutter

 . . . .Carrier gas (e.g., helium, argon) purity of 99.999%, or minimum 99.995%

when the appropriate carrier gas trap is installed. Contact INFICON for
carrier gas trap assistance.

NOTE: A pressurized [>16,547 kPa (>2,400 psi)] 50 liter tank of carrier gas will

last approximately one year or more.

 . . . .Dual Stage Regulator for pressurized carrier gas tank with outlet pressure

regulated to 400-427 kPa (58-62 psi). A Swagelok 1/8 in. fitting is preferred on
the regulator outlet to connect the carrier gas feed tube to Micro GC Fusion.

NOTE: In North America, use the CGA 580 inlet connection (PN 952-416-P1)

for helium, nitrogen and argon carrier gas. Use the CGA 350 inlet
connection (PN 952-415-P1) for hydrogen carrier gas. For installations
outside of North America, use the appropriate inlet connections as
standard for the region.

Exceeding 427 kPa (62 psi) carrier gas pressure may result
in instrument damage.

Calibration Gas

 . . . .Supply of calibration gas specific to the analysis from a commercial gas supplier.

 . . . .A regulator, if necessary, to reduce calibration gas pressure below

NOTE: 3 m (10 ft.) of pre-cleaned GC grade copper tubing is included with

Micro GC Fusion. Additional copper tubing is available in the installation
kit (PN 952-021-G1), or can be ordered in 15 m (50 ft.) lengths
(PN 5180-4196).

NOTE: Do not clean copper or stainless steel tubing with solvent.

NOTE: Do not use Teflon

including nuts and front and back ferrules. Typical size is 1/8 in. but adapters for
1/4 in. to 1/8 in. may be needed if 1/4 in. tubing is used.

NOTE: Calibration gas must be available at the time of installation.

NOTE: Calibration gas must closely resemble the composition of the actual

process gas.
