To prepare rocks as aqueous solutions, samples are digested using a closed system Teflon vessel PicoTrace Disollution Unit capable of digesting batches of 16 to 32 samples simultaneously (to temperatures of 180°C and 20 bars). The acids used for digestion are double-distilled using the PicoTrace or Savillex acid distillation system, and acid dilutions are made with 18.2 MΩ deionized water delivered by an ultra pure water polishing system.
