描述

應用

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.

Please visit the Reference Material Quality Grade websiteto find a comprehensive overview of our different grades of standards.

特點和優勢

• 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
