Let’s talk standards.
Our standards are traceable to certified materials. Each analytical standard and reference material is prepared and certified by the process of Gravimetric Documented Addition.
Our balances are verified with NIST traceable weights before and after each preparation. And our high-purity stock reagents are stored in a carefully controlled environment, preventing degradation and moisture absorption.
These practices and our Certificate of Guarantee promise you’ve established the most-accurate laboratory practices.
