Aqueous Inorganic Environmental Reference Materials
Aqueous Inorganic or elemental contamination in the environment occurs as a result of natural processes including erosion and volcanic activity, as well as human activities such as industrial processes.
We provide an extensive line of high-purity single and multi-element aqueous inorganic reference materials and CRMs for both research and analysis by AA/GFAA, ICP, ICP-MS, IC, wet chemistry techniques, and QC applications. The range includes key heavy metals such as Cadmium (Cd), Chromium (Cr), Lead (Pb), Mercury (Hg), and Arsenic (As).
