1. A process for synthesizing labeled compounds with an isotopic element, comprising the steps of:

  • preparing a labelling agent;

    labelling a precursor with the labelling agent, wherein the precursor is a protected substrate;

    pre-purifying the labelled precursor;

    retaining the labelled precursor on a solid support;

    deprotecting the labelled precursor, wherein deprotecting the labelled precursor converts the labelled precursor into a labelled compound in a deprotection step, wherein the labelled compound is free of the solid support; and

    formulating a final solution, wherein the deprotection step is performed directly on the solid support which is contained in a column or cartridge and wherein the labelled compound is 2-[18F]fluoro-2-deoxy-D-glucose (FGD).
