Carrier gas and transfer lines used are made up of copper tubing. GC copper columns are constructed from copper tubing. The tubing is generally 1/8 inch to 1/4 inch in diameter and 1 or 2 meters long which may be filled with tiny polymeric spheres coated with same kind of stationary phase.
Application
Copper tubing may be used in construction of esterification apparatus. Copper tubing may be crimped around the metal tubing with the ends of the cryotrap to enhance electrical connection.
