Clean-Cube
Thermo Conditioner for TDS Tubes
Absolutely clean TDS tubes are essential for a highly sensitive and reproducible measurement using thermal desorption. Here you can apply the CLEAN-CUBE to remove impurities from the tubes before they are used for sample collection: Up to 20 tubes are heated simultaneously under precisely controlled conditions. For high purity requirements a gas filter can be added at the purge gas in-port; for preventing laboratory air contamination, a charcoal filter can be inserted at the purge gas out-port.
The conditioning procedure is completely independent of the TDS system so that the CLEAN-CUBE saves time and protects GC column and detector.
Procedure
For the conditioning procedure, the tubes (industry standard 1/4" x 3.5") are inserted into the CLEAN-CUBE base plate. The upper cube part with the heating block is pushed down and the conditioning cycle starts.
A temperature program is started enabling temperatures up to 400 °C and the sequence of three ramps. This depends on the sorbent as well as the type of monitoring for which the tube will be used. The thermo conditioner provides default methods and the possibility to save individual temperature programs.
At the end of the conditioning cycle, the heating block is moved up while the purge gas is still flowing. This provides fast cooling of the tubes and also saves time. An automatic gas shut-off is implemented stopping the purge gas flow as soon as the tubes are removed.
- Up to 20 TDS tubes (1/4” x 3.5 “) can be conditioned with inert gas
- Temperature programming (3 ramps, max. 400 °C)
- Method storage
- Fast cooling down and automatic gas supply shutdown when tubes are removed
- Time and cost-saving device for it is independent of the TDS system
