Conversions: 1 psi = 6.8947 kPa = 0.068947 Bar = 0.068 ATM
Notes:
• If you have not requested option 305, you must supply
pre-cleaned, 1/8-inch copper tubing and a variety of 1/8-inch
Swagelok fittings to connect the GC to inlet and detector gas
supplies.
• If you purchased automated valving, the valve actuation
requires a separate pressurized, dry air supply at 380 kPa
(55 psig). This air supply must end in a male fitting
compatible with a 1/4-inch id plastic tube at the GC.
• Never use liquid thread sealer to connect fittings. Never use
chlorinated solvents to clean tubing or fittings.
