We assay our ICP standards and ICP-MS standards by validated ICP and wet chemical procedures to obtain the certified value. All standards we make for ICP and ICP-MS are traceable specified NIST SRMs. The NIST-traceable density is shown on the Certificate of Analysis, along with 3-4 pages of additional data.
Unless otherwise specified, chromium is present in our products as chromium (III).
All Single-Element Standards manufactured by Inorganic Ventures use high-purity starting materials and are produced in accordance with our stringent Quality Assurance guidelines.
All EPA Standards manufactured by Inorganic Ventures use high-purity starting materials and are produced in accordance with our stringent Quality Assurance guidelines.
All Multi-Element Standards manufactured by Inorganic Ventures use high-purity starting materials and are produced in accordance with our stringent Quality Assurance guidelines.
Unless otherwise specified, chromium is present in our products as chromium (III).
Anything not covered above (filter discs, QC analytes, and more)
Multi-Element solutions for instrument optimization
Elements, speciations, isotopes at your concentrations
Cations and anions at your concentrations
Custom standards are Inorganic Ventures’ specialty. Our catalog reveals only a fraction of the inorganic reference materials we can prepare. More than two thirds of our business is devoted entirely to preparing custom standards. As the leading manufacturer of custom inorganic standards, we’ve produced tens of thousands of unique blends for laboratories worldwide. It’s our area of expertise, and perhaps the most prominent way in which we flex to your specs.

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.
We’ve conducted stability studies on all standards, including blends. Compatibility and stability have been demonstrated and fully documented.
