The CatCart® Changer is an automated system for alternating between different catalyst cartridges whilst working in a flow chemistry environment using ThalesNano H-Cube series reactors.
The 6-channel CatCart® Changer works by switching the flow from one cartridge to another ‘on the fly’, enabling the user to run samples on up to 6 different catalysts at temperatures and pressures of up to 100°C (212°F) and 100 bar (1450 psi), respectively.
When combined with the H-Cube Pro™, the CatCart® Changer allows the easy screening of a selection of catalysts as well as reaction optimization. When used with the H-Cube® Pro in conjunction with the Autosampler™, it gives the possibility for screening and optimization to be run on a fully automated basis and for simplified sample injection and fraction collection of the end product.
How does it work?
A 6-channel valve, operated either through the H-Cube® Pro, or in conjunction with the Autosampler™ integration software via PC, controls the flow of the compound into any of the 6 CatCart® chambers in the CatCart® Changer. The temperature and pressure can be set individually for each catalyst.
The CatCart® Changer has a number of useful applications:
Using a different catalyst in each chamber enables up to 6 catalysts to be screened with a particular compound.
With the CatCart® Changer, with the same catalyst in each chamber pre-set to different temperatures and pressures, the optimization process occurs without any manual intervention. Using the Autosampler™, the different fractions can be collected and sorted for analysis.
Using the same catalyst in each chamber, a library of compounds can be synthesized in an automated environment without fear of catalyst deactivation. This is achieved through continually directing the compound through a new, fresh CatCart® at pre-set intervals, ensuring that the catalyst does not deactivate during the library production.
Using the same type of CatCart® in all holders, a large amount of the desired compound can be prepared: the substrate is changed to a fresh cartridge after a user specified amount of time.
