Acids, Alkaline Solutions and Water for trace analysis via ICP-OES, ICP-MS, AAS and IC
Carl ROTH provides two high quality product lines, ROTIPURAN® Ultra & Supra specially for research, trace analysis and electronics. These ultrapure reagents are produced using a technologically complex distillation process (subboiling distillation) and are filled only into specially selected, suitable containers under clean room conditions. Very extensive production and quality controls guarantee extremely high quality.
This supra quality line (ppb-quality) is perfectly suitable for sample preparation in trace analysis (e.g. via ICP-OES, AAS, IC, etc.). Over 60 elements are specified and their content is below 1 ppb [parts per billion =10-9]. Bottled and delivered in special plastic bottles. The certificates of analysis are available online.
