Connecting the Oven Cryogenic System

Oven Cryo System with Carbon Dioxide Connection

Thermo Scientific
If the oven of your TRACE 1300/TRACE 1310 is equipped with a cryogenic cooling option,
you need a supply of coolant, such as carbon dioxide (CO
This Oven cryo system consists of a tube for carbon dioxide inserted into the oven and fitted
with a 1/8-in. solenoid valve for carbon dioxide mounted into the back of the GC.
Carbon dioxide must be supplied in a high-pressure cylinder with a dip tube. It is your
responsibility to ensure the delivery connection from the carbon dioxide cryogenic supply is
adaptable to 1/8-in. tubing.
configuration.

Dip tube
CAUTION High pressures and extremely low temperatures make pressurized carbon
dioxide a hazardous material. High concentrations of carbon dioxide are dangerous.
To avoid injury, always follow the safety precautions and delivery system design
recommended by your gas supplier.
 To connect the cryogenic system to the carbon dioxide supply
1. Connect the proper end of the cryo supply tube to the 1/8-in. NPT connection of the
solenoid valve using the proper nut and ferrule. Use a 7/16-in. wrench to tighten the
fittings. See Figure 14.
