Quality Assurance

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

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

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

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

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

Clean Rooms
Their eco-friendly laboratories have been specially planned and constructed to be contamination-free during every stage of production. They use ULPA filtered clean rooms for the manufacturing of certified reference standards, various R&D projects and other special purposes. They keep their ICP-MS instrumentation in these ultra-modern clean rooms.

Product Documentation
Their ISO Guide 31-compliant Certificates of Analysis are the most detailed in the industry. They include valuable information such as trace metallic impurities and uncertainty levels, as well as the results of every QC step. Additionally They supply MSDSs and instruction sheets (available with most Water QC products) to help everyone from a recently trained technician to the most experienced scientist.

Packaging
Every LDPE, HDPE, PVC, glass, and teflon bottle is processed by chemical treatment, plus full UV inspection for contaminants. Products are dispensed, sealed and documented for shipment to your exact specifications.
