Posi RAM: Radio-HPLC detector for PET metabolites
Designed specifically for the detection and quantitation of low-level PET metabolites in the presence of higher levels of a single substance, therapeutic agent, test compound, or substrate.
Posi-RAM™ uses two bismuth germanate (BGO) crystals mounted on matched photomultiplier tubes with a flow cell between them to achieve the highest possible sensitivity. By using fast coincidence electronics, an event is recorded only when each detector assembly detects an event within the time allotted for coincidence.
The resulting low background levels and unparalleled signal-to-noise ratio enable low-level detection and quantification of PET metabolites.
