Small animal PET cameras with high spatial resolution and high sensitivity are also useful, beyond their original pre-clinical application, in the following of surface chemical and the physicochemical processes. The purpose of this study was the introduction of the three-dimensional real-time PET based visualization method in separation processes. The separated tracer compounds can be followed and displayed in three dimension along chromatography column using the PET technique. We studied the separation of 11C-labeled methanol and 11C-labeled methyl iodide using reversed-phase high performance liquid chromatography (HPLC) on semi-preparative and analytical columns in order to determine the detection limits of our PET camera (MiniPET). The PET imaging is suitable for analyzing the column efficiency and the underlying processes in the liquid chromatography. Synthesis, separation and quality control of PET radiopharmaceuticals are performed in radiochemistry labs (in PET Centers) with the help of the liquid chromatography, therefore equipment, infrastructure and other lab conditions are usually available for researchers and for private companies to study chromatographic separation processes and to develop columns.

A peak structure has been observed which is dominated by a broad cusp attributed to the zero-energy electron emission in the projectile-centered reference system at the 2S3 excitation threshold of He0. Further narrower peaks have been identified as results of the decay of autodetachment resonant states of He- populated during the collision by three-electron bound-state capture. © 2016 American Physical Society.
