Application

The Standard Reference Material (SRM) is primarily intended for use as an internal standard in X-ray fluorescence spectrometry (XRF) for measuring sulfur in oils and other liquid hydrocarbon matrices.

Features and Benefits

  • NIST certified value for sulfur content is reported based on analyses by isotope dilution thermal ionization mass spectrometry (ID-TIMS)
  • Maintenance and expiration of SRM certificate, instructions for use are provided on the NIST certificate.
