c. Plug the power cable to the AC Input connector on the front of the module and to
the wall outlet. The LED marked On lights up after the GC power on.
Note For further details regarding the installation of the Aux Temperature/Cryo module,
see the section "Adding an Aux Temperature/Cryo Module"
This cryo system consists of a tube for liquid nitrogen inserted into the PTV/PTVBKF
module and fitted with a 1/8-in. solenoid valve for liquid nitrogen mounted on a bracket
fixed on the back of the GC. The tube for liquid nitrogen is covered with an insulating
material tube. See Figure
Figure 23. PTV Cryo System with Liquid Nitrogen
Liquid Nitrogen must be supplied at a pressure of 1.5 bar (150 kPa; 21.75 psig). Plumbing to
the GC should be 1/4-in. copper or stainless steel tubing with insulation.
It is your responsibility to ensure the delivery connection from the Liquid Nitrogen cryogenic
supply is adaptable to 1/4-in. tubing. The liquid nitrogen cryogenic valve on the GC is a
1/4-in. Swagelok fitting.
Figure 24 shows the proper configuration for a liquid nitrogen tank.
