Preparation of High Purity Methanol or Other Reagents


For some radiochemical processes, currently available reagents contain impurities that interfere with low level analyses. For example, analytes of interest have been found in commercial methanol reagents, causing an increase in the analytical background. Reagents must then first be distilled to remove impurities prior to analysis, greatly increasing analysis times. Acetonitrile is another example of a reagent that is needed at ultra-high purity for analytical chemistry. Commercially available ultra-high purity reagents in containers of appropriated material (e.g. Teflon) would eliminate these time consuming steps and improve the overall efficiency of the process.
