CLEARLY THE WISEST DECISION YOU WILL MAKE
WE HAVE STANDARDS TO SUPPORT YOUR WASTEWATER TESTING WITH CONFIDENCE
NSI 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.
Interested in our GGA Concentrate Snips™?
To use, simply snip open the tube and pour contents directly into a 300mL BOD bottle. No measurements are required and no contamination is possible. Watch the video below for a full product demonstration!
Our Wastewater Standards Are Convenient & Easy-To-Use
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.
