EPA Standards

EPA Standards for ICP and ICP-MS

All EPA Standards manufactured by Inorganic Ventures use high-purity starting materials and are produced in accordance with our stringent Quality Assurance guidelines.

 

Standards you can trust

Traceable
We use NIST Standard Reference Materials (SRM and lot number specified on the certificate) for calibration and direct comparison.

Precise
We have detailed Error Budgets that define the errors used in determining the uncertainty, giving us a unique value for each lot of material.

Pure
We use ICP and ICP-MS to check the purity of all CRMs. Protocols are prepared for all new starting materials. We perform purifications and chemical modifications as required to meet predefined quality specifications.

Accurate
We use two independent validated assay methods that are performed with a reliable QC standard.

Stable & Compatible
We've conducted stability studies on all standards, including blends. Compatibility and stability have been demonstrated and fully documented.
