Device for preparing combustible samples containing compounds labeled with 3h and 14c for measurement of their radioactivity
Abstract
Abstract A DEVICE FOR THE PREPARATION OF COMBUSTIBLE SAMPLES CONTAINING COMPOUNDS LABELLED WITH 3H AND 14C FOR SEASURING THEIR RADIOACTIVITY IN A LIQUID SCINTILLATION COUNTER DEVICE. THE DEVICE INCLUDES A TRANSPORT DEVICE WHICH ADVANCES ANY NUMBER OF FLASKS INTO POSITION WITH RESPECT TO A BURETTE, A COMBUSTION CHAMBER, AND A SEALING AND NUMBERING DEVICE. THE FLASKS RECEIVE A CHARGE OF SCINTILLATOR SOLUTION FROM THE BURETTE, AN ABSORBER SOLUTION CONTAINING COMBUSTED SAMPLES FROM AN ABSORBER WHICH IS CONNECTED BY AN APPROPRIATE VALVE TO THE COMBUSTION CHAMBER, AND A SEAL FROM THE SEALING AND NUMBERING DEVICE. THE COMBUSTION CHAMBER INCLUDES A HOLDER FOR CARRYING THE SAMPLES, AN ELECTRIC IGNITION DEVICE AND AN INJECTION DEVICE FOR FLUSHING THE COMBUSTION CHAMBER AFTER COMBUSTION. TO COORDINATELY CONTROL THE ACTIVITY OF THE VARIOUS PARTS OF THE DEVICE A CONTROL UNIT IS PROVIDED.
