Certified Heavy Metals (for analysis)

Certified Heavy Metals (for analysis) are analytical reference materials containing precisely defined concentrations of regulated metallic elements such as lead, cadmium, arsenic, mercury, and chromium. They are used by laboratories for instrument calibration, method development, and routine QC across techniques including ICP-MS, ICP-OES, AAS, and XRF. Key performance features include traceable concentration values, verified stability, and consistent lot-to-lot reproducibility for reliable trace-level quantification. Typical downstream users include pharmaceutical QC labs, food and beverage testing facilities, environmental monitoring agencies, water treatment operators, and contract research organizations supporting regulatory compliance and impurity screening programs.
