Reference Materials

Reference materials are well established for use in the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials. It is absolutely essential to maintain the accuracy and precision of analytical measurements and important to prevent imprecise values, especially during instrumental qualification and calibration. As analytical technology improves, certified reference materials are gaining in importance in terms of clear traceability information. Under the brand CertiPUR^®, Merck offers a range of first-class reference materials for all analytical methods. Ready-to-use, comparable and officially certified results are additional criteria with which CertiPUR^® meets the requirements e.g. in calibration for instrumental analysis via atomic absorption spectroscopy (AAS) or inductively coupled plasma spectroscopy (ICP). Another plus point of all CertiPUR^® reference materials, beside their high precision, is the fact that they are traceable to national and international standards. CertiPUR^® is the only standard that gives you reliable measuring results – your best choice for highest quality requirements.

Your benefit: Reliability, Excellence, Improvement.

Reliable calibration

CertiPUR^® reference materials are a class of its own, particularly when there is a need for correct measuring results. CertiPUR^® products shows precise and reliable values. The quality of CertiPUR^® ICP, pH and conductivity standards products are officially certified by an accredited calibration laboratory and this accreditation is recognized worldwide.

Excellent application possibilities

CertiPUR^® is the ideal material for use in all analytical methods. Accuracy and traceability, especially for the reference materials, is gaining in importance with respect to the accuracy and precision of analytical measurements. CertiPUR^® is employed for reliable calibration in conductivity measurement, in ion chromatography, in pH measurement, in UV/VIS spectroscopy, in volumetry, etc...

Improve your measuring results

Calibration is the best basis for correct functioning of the device and it is the first indispensable step. Ongoing product innovations, call for additional and optimized control. Measurement correctness and validity of the quality control have to be met, the reference materials have to assure accurate and comparable results. All of that is not a problem since precise values can be realized with CertiPUR^®. The outstanding standard comes accompanied with a certificate of analysis as a ready to use solution.
