 . . . .Moisture/hydrocarbon trap (PN G2870A-01) required for the carrier gas when
using Molsieve or Alumina columns.
CAUTION
To protect Micro GC Fusion and to enhance performance,
carrier gas traps should be used to purify the carrier gas
before introduction into Micro GC Fusion.
A hydrocarbon/moisture trap (PN G2870A-01) is usually
sufficient.
 . . . .Copper or stainless steel tubing (pre-cleaned) 1/8 in. OD for carrier gas
connections between the tank regulator output and Micro GC Fusion carrier
gas inlet. Micro GC Fusion has up to two 1/8 in. Swagelok male carrier gas
inlet connections.
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
® or Tygon ® tubing for carrier gas.
 . . . .Assortment of male and female Swagelok fittings for regulator, tubing, etc.,
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.
 . . . .1/8 in. tee fitting and 1/8 in. ball valve, depending on connection requirements.
Calibration Gas
 . . . .Supply of calibration gas specific to the analysis from a commercial gas supplier.
NOTE: Calibration gas must be available at the time of installation.
NOTE: Calibration gas must closely resemble the composition of the actual
process gas.
 . . . .A regulator, if necessary, to reduce calibration gas pressure below
69 kPa (10 psi) at the Micro GC Fusion inlets. The regulator must be clean,
grease-free and non-venting.
NOTE: Checkout gas mixtures are only used for instrument installation
and start up.
NOTE: Checkout gas mixtures supplied by INFICON are not calibration gases.
