duoPUR Acid Purification System allows laboratories to purify low-cost reagent grade acids

High-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.
