アプリケーション

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

特徴および利点

• 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
