Beschreibung

General description

Erfüllt die Spezifikationen der ASTM B-280.
(ASTM ist die American Society for Testing and Materials.)

Carrier gas and transfer lines used are made up of copper tubing.[1] 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.[2]

Application

Copper tubing may be used in construction of esterification apparatus.[3] Copper tubing may be crimped around the metal tubing with the ends of the cryotrap to enhance electrical connection.[4]
