Flash Pyrolysis Platform™
Faster and greener chemistry
While a number of methods are available to organic chemists for the synthesis of novel structures, it has also been shown that they employ a relatively small chemical technology toolbox, which limits the potentially available chemical space in conventional laboratories all around the world. This is especially true once extreme process conditions are applied in order to attain the desired (and in most cases novel) compounds.
In response to these limitations and needs we offer the Flash Pyrolysis Platform™, which reaches beyond the already known capabilities of the usual vacuum flash pyrolysis instruments by enabling the users to apply volatile and non-volatile starting materials as well.
How does it work?
Flash Vacuum Pyrolysis (FVP)
During the course of the FVP applications, the system is kept under vacuum, while the starting material is introduced mostly in a micronized solid state. Due to the applied conditions (high temperature and vacuum) the FVP applications facilitate the occurrence of mostly unimolecular reactions where the materials (in gas phase) pass through the reactor in milliseconds.
In FVP mode, the starting material is distilled through the furnace in a quartz reactor tube, while it is exposed to pyrolytic conditions in the furnace under vacuum. The precursor sublimates through the system by a preheater mounted onto the furnace, and the products are then condensed by cold traps afterwards.
Apart from the fact that the vacuum may avoid adverse chemical reactions, it may also decrease the boiling point of the precursors in the preheater, helping the starting material to be sublimated through the system too.
Continuous Liquid Spray Vaporization (CLSV)
In the case of the CLSV methods, the starting material is dispersed in a chosen solvent that is sprayed through the system using a carrier gas.
In CLSV mode the applications do not require the presence of a vacuum and the substrate does not have to be volatile, as it is dissolved and sprayed through the reactor tube via a nozzle under continuous nitrogen flow. Finally the samples are collected using the cold traps.
