33. Gas separation column 1
pcs DURAN®, enables a didactic gas chromatograph to be set up for the low
temperature ranges up to 100°C. The gas separation column is suitable to demonstrate the principle of gas chromatography separations at room
temperature separating agent: Dinonyl phthalate on kieselguhr; carrier gas: hydrogen or helium. By inserting the gas separation column
in the glass jacket, it can be tempered in the range between 10 and 100 °C. With the aid of a measuring probe, a control unit and an interface system or
a Yt-recorder the composition of gas or liquid mixtures can be investigated and recorded using a gas chromatograph.
Technical data: • Total length of the insert: 310 mm
• Length of the separation column spiral shaped: approx. 1.3 m
• Outer diameter of the glass cylinder: 36 mm
• Length of the connection tube: 55 mm • Outer diameter of the connection tube:
