Simple automatic quality control for radiolabeled gases for PET

Quality control of routine radiopharmaceutical preparations of carbon monoxide, carbon dioxide and oxygen is necessary. Still, this simple task is compromised by the high demand for gas chromatograph (GC) time in a busy laboratory. Frequent production of such materials at essentially random intervals requires a dedicated radio-GC system. We report a simple, inexpensive and automatic routine quality control approach that is continuously available independently of the main laboratory instrument and provides the same accuracy.
