Certified Reference Materials manufactured by Inorganic Ventures

ISO 17034 "General Requirements for the Competence of Reference Materials Producers" certifies that we meet every requirement for competence in the very specific field of Reference Material Production. Accreditation to ISO 17034 involves not only technical competence and good quality management practices, but adds verification of critical production management specific to reference material producers. We've been accredited to ISO 17034 (and its predecessors) longer than any other inorganic standards manufacturer.

Unless otherwise specified, chromium is present in our products as chromium (III).
