Error-free results with analytical quality assurance

With the Spectroquant® analysis system Merck Millipore offers a complete analytical quality assurance (AQA) concept for all Spectroquant® photometers.

This allows users to be sure at all times that laboratory processes are running within defined minimum margins of error from beginning to end, providing reliable measurement results.

Merck Millipore's ammonium standard solutions for photometric applications have an expanded measurement uncertainty of no more than 0.012 mg/l.
