Quality Assurance

High-Purity Standards has an inherent focus on providing quality assurance to its customers. Whether its meeting ISO standards, certifying reference materials, and of course, qualifying inorganic standards to be NIST traceable, providing our customers with vetted certificate of analysis is of the utmost importance.

Meeting ISO Standards

High-Purity Standards understands a comprehensive quality system is key to our customers’ confidence in the products that we manufacture. That is why we developed our Total Quality System with the help and assessment of independent agencies. We are certified by Perry Johnson Registrars to ISO 9001:2015 and accredited by ANAB to ISO/IEC 17025:2017 and ISO 17034:2016.

Comprehensive Product Testing

At High-Purity Standards, being called a Certified Reference Material requires extensive testing including:

  • Certified value assignment
  • Batch homogeneity testing for each lot
  • Long-term and short-term stability testing

NIST Traceability

For inorganic standards, the scope of HPS ISO 17034 certificates has been limited to only those products that can be validated against the NIST Standard Reference Material 3100 series. This validation process meets the requirements established by NIST for maintaining direct NIST Traceability.

National Institute of Standards and Technology (NIST)

Where NIST Standard Reference Materials do not exist, HPS uses second sources provided by reputable CRM suppliers to provide an independent validation of products. Consequently, the certificate for these products will not include an accredited body endorsement. HPS distinguishes between Certificate of Analysis by only placing AB endorsement on products that pass the most rigorous testing for traceability.

Reading the Certificates of Analysis

Each CofA provides detailed and specific information as to the extensive analysis behind the manufacturing of each product. HPS uses the best practices throughout this process, but should you encounter a discrepancy or concern we would welcome your phone call.
