14-CO2 can be adsorbed on stainless steel traps at room temperature. Heating of a trap with adsorbed 14-CO2 results in release of 14-CO2 to an equilibrium pressure depending on the temperature of the trap. The chemical reaction with 14-CO2 is performed using a manifold system of stainless steel. After the reaction, surplus 14-CO2 can be readsorbed on the trap for further use.
Storage of 14-CO2
Traps for 14-CO2 storage are made from stainless steel . They can reversibly adsorb 14-CO2 with high efficiency and low equilibrium pressure at room temperature.
14-CO2 Manifold System
RC TRITEC has designed high-vacuum manifold systems for the handling of 14-CO2, based on the long experience with tritium handling systems. The manifold consists of a connector to a vessel for the production of 14-CO2, two traps to adsorb 14-CO2 and connectors for the reaction vessel and a distillation ampoule or a NaOH trap. In addition there is supply of an inert gas, a Pirani gauge and an absolute pressure sensor (0 - 4000 mbar).
The reaction branch with two connectors offers the optional removal of solvents by freeze-drying them over into a separate glass ampoule. It also enables the absorption of surplus 14-CO2 into a NaOH solution, if the solvent cannot be removed on account of its high boiling point, which precludes its removal by freeze-drying - this is essential before re-absorption of the gas onto the trap.
The use of two traps on the manifold system offers additional safety and manipulation options.
Advantages of the Stainless Steel Manifold System
|14-CO2 need not be generated from carbonate for each experiment.
|The 14-CO2 pressure can be adjusted by setting the temperature of the trap.
|Option to work at elevated 14-CO2 pressure.
|Surplus 14-CO2 can be readsorbed from the vacuum system after the reaction. Discharges to the environment are reduced to a minimum.
|All stainless steel components guarantee the highest safety and reliability at maximum leak tightness.
|14-CO2 can be purchased on stainless steel traps from RC TRITEC, enabling you to reduce handling risks and to produce less radioactive waste.|
