NSI by ZeptoMetrix is a globally trusted brand for laboratory quality control standards and proficiency tests. Use of our Certified Reference Materials (CRMs) and Proficiency Tests (PT) Standards on a routine basis to monitor analytical performance will defensibly document data quality and support accreditation requirements.  We are laser focused on developing, manufacturing, and delivering unique ISO-accredited certified reference materials (CRMs) that are not only stable but are also easy to implement into routine testing work streams.  Some unique wastewater product concepts include:

• Pre-measured, single-use reference materials that prevent laboratory errors and re-work.
• Ready-to-use CRMs requiring no preparatory steps to save time and effort.
• Cocktailed, multi-parameter CRMs that can be used for numerous types of testing procedures. Thus, reducing the number of CRMs needed in the typical laboratory.
