The European Pharmacopeia is moving away from the historical thin layer chromatography technique for the determination of Ninhydrin-positive substances, to more specific and sensitive methods utilising Liquid Chromatography (LC) or Amino Acid Analysers.
Cleaning capillary tubes with 35% H2O2 + muriatic acid mixture. From time to time we often run out of clean capillary tubes what are important if we would like to check our reactions and products purity with TLC (thin layer chromatography). The H2O2 and HCl mixture is a strongly oxidizing solution, what also dissolves gold (yes, not just aqua regia is suitable for this) and it also destroys everything what is organic, so it is perfect to clean glassware. Important note: elemental chlorine…
