• Resumen

  • A recent suggestion to visualize spots on thin layer plates by applying phosphomolybdic acid reagent with a cotton ball (1) may not be suitable for all visualization reagents especially concentrated sulfuric acid. If spraying a reagent with a power pac type device is preferred for this or some other reason, we suggest spraying the reagent inside of a twist tie-sealed, clear-plastic kitchen garbage bag. In this way, spray reagents are completely contained obviating the need for spraying the plates in a fume hood, and cleanup is simple.
