This Spectroquant®Ammonium Standard Solution is a high-quality laboratory solution used forinternal quality control and method controlling purposes.

These Spectroquant® standard solutionsperfectly complement our ready-to-use test kits and photometers within theSpectroquant® portfolio and are ideal for validatinginternational norm methods described in e.g., ISO, EN, APHA, and EPA.

  • Ready-to-use diluted reference materials (RMs) along with expanded measurement uncertainty ensure absolute precision
  • Accompanied with a certificate of analysis (COA) detailing the certified values, including uncertainty and expiry date
  • Directly traceable to standard reference materials (SRM) from the National Institute of Standards and Technology (NIST) or to United States Pharmacopeia (USP)
