描述

一般說明

This Spectroquant™ Nitrite Standard Solution is a high-quality laboratory solution used for internal quality control and method-controlling purposes.

These Spectroquant™ standard solutions perfectly complement our ready-to-use test kits and photometers within the Spectroquant™ portfolio and are ideal for validating international norm methods described in e.g., ISO, EN, APHA, and EPA.

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

應用

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

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
