AAS Standards & Modifiers

If Atomic Absorption is your instrument of choice, we think you'll appreciate our improved line of AAS standards. We've more than doubled our previous selection of analytical elements. And if you still can't find what you need, just ask . Custom manufacturing is our specialty.

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.
