     Batch-specific certificates for your quality management procedures
     We constantly monitor the adherence to all specifications in our laboratories.
     The elaborate instrumental and wet chemistry procedures are constantly adapted and
     updated in accordance with technical and methodical developments. Certificates of
     analysis can be found for all our products on the Internet under www.chemdat.de.
               Our certificates of analysis contain all batch-related analytical values for
     the relevant substance. They also state the trace impurity content, if detectable, as an
     absolute number.
               Please contact us if you require reagents with specifications that are not
     included in our certificate of analysis for your tasks. We will be glad to advise you.
