External Quality Control: Spectroquant® Round Robin Test Solutions
Internal Quality Control (IQC) is essential – but not enough. To establish the validity and accuracy of their photometric methods and analyses, laboratories also need External Quality Assurance (EQA), confirmed by an impartial institute. MilliporeSigma makes the job easier and your results safer by offering you a complete EQA service.
To demonstrate the competence of your photometric methods, you are required to test a sample with an unknown content of a certain parameter. Our Spectroquant® Round Robin test solutions are optimized for this purpose. These multi-parameter standard solutions have undisclosed values, and only provide information regarding the parameters included and the possible concentration range of the result. After you have completed the analysis, your results are evaluated by AQS Baden-Württemberg, Institute for Sanitary Engineering at Stuttgart University in Germany. They provide you a detailed feedback about the accuracy of your photometric methods, as well as a certificate stating whether results were within expectations. MilliporeSigma uses this independent institute to secure the transparency and validity of your EQA.
