应用
Ammonium Standard Solution can be used to check the photometric measurement system (reagents, measurement device, handling) and the mode of working.
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.

特点和优势
- Manufactured and tested in DIN EN ISO 9001:2008 accredited laboratory
- The solution is pre-diluted to a concentration that falls into the range of our Spectroquant® test kits. This eliminates the need for dilution prior to analysis and hence avoids a common source of error
- 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)
- Reliable and reproducible results
