The present invention provides a simplified method for the preparation of 18F-labelled compounds that is particularly suitable for automation. The method of the invention is specifically applicable where the 18F-labelled compound is prepared from a labelling precursor that comprises protecting groups and wherein the synthetic route to the final compound includes removal of these protecting groups by acid or alkaline hydrolysis. Also provided by the present invention is a cassette useful for carrying out the method of the invention in an automated manner.

A convection-free flow-type reactor includes a reactor body. The reactor body includes a reaction chamber to house a fluid. An inlet is in communication with the reaction chamber to allow input of a reactant fluid. An outlet is in communication with the reaction chamber to allow output of a product fluid. An energy beam source device provides an energy beam to irradiate the reactant fluid in the reaction chamber. The disclosure further provides a convection-free flow-type synthesis method.

In view of the needs of the art, the present invention provides a reaction vessel having two distinct compartments, for separating solid-supported reagents. The present invention also provides a method to perform two step radiochemistry procedures in one reactor in a clean and 10 efficient manner. An example of the chemistry that could benefit from this approach is ‘click’ radiochemistry. The present invention provides a method to form the synthon, and react it with an alkyne without the need to perform a purification step.

An automated radiosynthesizer device includes a plurality of reactor assemblies, each reactor assembly being operatively connected to a horizontal actuator for moving the reactor assembly in the horizontal direction and a vertical actuator for moving the reactor assembly in the vertical direction. A plurality of disposable cassettes are disposed above each of the plurality of reactor assemblies, each cassette comprising a lower surface comprising a plurality of sealed and un-sealed gaskets, wherein the un-sealed gaskets are connected to internal fluid paths within the cassette. The device includes a three-axis reagent and gas handling robot disposed above the plurality of cassettes and terminates in a vial gripper and a gas manifold having an inert gas port and a vacuum port. The device includes a control system configured to control the horizontal actuator and vertical actuator of each reactor assembly and the three-axis reagent and gas handling robot.

The present invention relates to an automated radiosynthesis device adapted for enhanced automatic disconnection of a disposable kit once a radiosynthesis has been carried out. The automated radiosynthesis device of the invention therefore reduces the time to remove the disposable kit from the radiosynthesis device and reduces radiation exposure to the operator.
摘要:
The present invention provides a system for evaporating a radioactive fluid, a method for the synthesis of a radiolabelled compound including this system, and a cassette for the synthesis of a radiolabelled compound comprising this system. The present invention provides advantages over known methods for evaporation of a radioactive fluid as it reduces drastically the amount of radioactive gaseous chemicals that are released in the hot cell. It is gentler and more secure compared to the known process and provides access to radiosyntheic processes that may not been acceptable for safety reasons related to release of volatile radioactive gases during evaporation. In addition, the process yields are higher because the radioactive volatiles are labelled intermediate species.
