Accreditation Update – SPEX CertiPrep Only:
SPEX CertiPrep is transitioning its accreditation body from A2LA to ANAB, with completion expected by February 2026. During this transition, you may notice a change in the accreditation logos displayed on Certificates of Analysis (CoAs).

Under ANAB policy, when a reference material producer holds accreditation to both ISO/IEC 17025 and ISO 17034, only the ISO 17034 accreditation mark may appear on the CoA. As a result, the ISO/IEC 17025 logo will no longer be displayed on SPEX CertiPrep CoAs.
