Patent number: 11094424Abstract: 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.Type: GrantFiled: August 29, 2019Date of Patent: August 17, 2021Assignee: GE HEALTHCARE LIMITEDInventors: Xavier Franci, Steve Lignon, Audrey Lange

Patent number: 10703771Abstract: The present invention provides a new chemical process, a new cassette configuration, and new software for the automated production of multiple batches of an [18F]labelled compound on a single cassette. The invention allows one synthesizer in one hot cell to produce sequentially a plurality of batches of [18F]-labelled PET tracer in the same day. In particular, the present invention provides a novel arrangement useful for the trapping of [18F]fluoride and recovery of [18O]water.Type: GrantFiled: November 12, 2015Date of Patent: July 7, 2020Assignee: GE HEALTHCARE LIMITEDInventors: Xavier Franci, Steve Lignon, Audrey Marie Lange, Nicolas Verbrugge

Publication number: 20150175553Abstract: 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.Type: ApplicationFiled: November 29, 2012Publication date: June 25, 2015Applicant: GE HEALTHCARE LIMITEDInventors: Ludovic Wouters, Steve Lignon

Patent number: 8366934Abstract: A method extracts out of an aqueous solution, concentrate and/or reformulate [18F] fluorides without any evaporation step. The eluting solution is a low water content, preferably <3% water, organic solution containing at least: a first compound (A) which is a tertiary alcohol-function bearing molecule, a second compound (B) which is a phase transfer agent suitable for radiolabeling and which is necessary to the anion exchange process.Type: GrantFiled: February 19, 2008Date of Patent: February 5, 2013Assignees: Trasis S.A., Universite de liegeInventors: Joel Aerts, Christian LeMaire, Steve Lignon, André Luxen, Jean-Luc Morelle, Gauthier Philippart, Samuel Voccia
