QA/QC & Analytical Techniques In-Depth Focus 2019 featuring Microbiology and Chromatography

• Changes to lab setups become necessary for many reasons, but the important role of quality control should remain consistently accurate. Tim Sandle and Kerry Skinner describe the details to consider when transferring an analytical method between laboratories or when changing your reagent supplier.
• Technetium-99m (^99mTc) is a synthetic radioisotope that is used worldwide to produce radiopharmaceuticals that are mainly used for diagnostic purposes in nuclear medicines. The purity of the final radiopharmaceutical (99mTc-R) can be confirmed by applying chromatographic methods. This method is based on different rates of movement of substances in a sample solution through a porous medium under the influence of a reagent (either a solvent or gas). Anastasia Petropoulou explores some chromatographic techniques used to identify impurities in radiopharmaceuticals based on ^99mTc.
