说明

一般說明

This Spectroquant^® CombiCheck 50 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

CombiCheck 50 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
