“In the preparation of high purity reagents, there is only one significant and practical choice for the method of purification: sub-boiling distillation.” – US EPA SW-846, Chapter 3, Update IVB.

Reagent contamination increases the background concentration of analytes present in a sample. Because of this, laboratories purchase expensive high-purity acids for trace metal (element) analyses. With small samples sizes, it is critical to keep blank levels low for good reproducibility. Milestone’s duoPUR and subCLEAN, sub-boiling distillation systems allow laboratories to make their own high purity acids at dramatically reduced costs.

Sub-Boiling Technology

The chemical reagents used during the analysis are an important source of the analytical blank. Sub-boiling distillation has been demonstrated to be the best method of acid purification. It uses contactless infrared lamps to vaporize the surface liquid at a temperature typically 20 °C below the boiling point.

With conventional distillation, the boiling of acid generates aerosolized particles, resulting in contamination of the distillate. In contrast to this, gentle surface evaporation during sub-boiling distillation prevents the formation of spray or droplets, yielding high purity acids.
