Certified Calcium Carbonate (for analysis)

Certified Calcium Carbonate (for analysis) is a high-purity inorganic reference material supplied to meet the stringent requirements of quantitative analytical work. It is widely used for instrument calibration, method validation, and routine quality control in techniques such as titrimetry, complexometric EDTA analysis, ICP-OES, ICP-MS, XRF, and thermogravimetric analysis. Its consistent composition, low impurity profile, and reliable traceability make it well suited for preparing calcium standards and verifying analytical accuracy. Typical downstream users include contract testing laboratories, pharmaceutical and food QC departments, environmental testing facilities, academic research institutions, and industrial R&D centers across the minerals, cement, and specialty chemicals sectors.
