Standards you can trust Traceable
We use NIST Standard Reference Materials (SRM and lot number specified on the certificate) for calibration and direct comparison.
We have detailed Error Budgets that define the errors used in determining the uncertainty, giving us a unique value for each lot of material.
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.
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.
