Representative column-switching HPLC radio-metabolite analysis of controls and experimental samples. Column-switching from capture-column loading to elution of the capture column onto the analytical column starts at t = 0 min. Radioactivity (blue) and UV (254 nm, red) spectra are shown overlaid. (a) Control sample plasma spiked with [18F]7; (b) control sample pancreas spiked with [18F]7; (c) 60-min post-injection in plasma; (d) 60-min post-injection in the pancreas
