Organic, Inorganic, Microbiology & PT Reference Materials for Environmental Testing

We offer organic, inorganic, microbiology, and proficiency testing (PT) reference materials for environmental testing. Choosing environmental reference materials from ZeptoMetrix means accurate and robust chemical and microbiological certified reference materials (CRMs). Our standards are certified for various environmental methods (e.g., EPA, Standard Methods, AOAC, ASTM). Every COA includes certified values for a variety of analytical techniques. We provide custom reference material manufacturing under ISO 17034. Our CRMs increase your laboratory’s efficiency and provide confidence in the accuracy of your results.
