duoPUR Acid Purification System allows laboratories to purify low-cost reagent grade acids
24 Oct 2022High-purity acids and reagents are critical to controlling the analytical blank, the “Achilles heel” of trace analysis, and to improving ICP-OES and ICP-MS detection limits. Reagent purity, cleanliness of the materials used in sample preparation, the laboratory environment, and the skill of the analyst are all factors that contribute to contamination. In this application note, Milestone presents the duoPUR and subCLEAN systems for cleaning reagent grade acids and avoiding the expense of purchasing the highest purity acids.

duoPUR Acid Distillation System
MilestoneduoPUR and subPUR, sub-boiling distillation systems allow laboratories to make their own high purity acids at dramatically reduced costs. Offering an optimal purification method, this type of acid distillation uses contactless infrared lamps to vaporize the surface liquid at a temperature typically 20°C below the boiling point. The duoPUR allows the purification of the most common acids such as HNO3 and HCl.
