Wastewater Standards

FINALLY. STANDARDS THAT WORK AS HARD AS YOU DO.

Wastewater Standards | Wastewater Treatment Plant banner image

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.
