Certipur® Reference Materials for Reliable
Measuring Results

For accurate results in instrumental analysis, it is essential to calibrate your equipment beforehand commencing work. However, such calibration work is only meaningful if reliable reference materials are employed. With Certipur®, Merck's comprehensive range of first-class certified reference materials (CRMs), you can have always confidence in your analytical results. Certipur® reference materials come with a comprehensive Certificate of Analysis (CoA) documenting all batch-specific parameters as well as important inspection-relevant data. Moreover, Merck is accredited as a Certified Reference Material producer according to ISO Guide 34 for our conductivity and ICP standards.
