General description

This certified reference material (CRM) is produced in accordance with ISO 17034 and characterized in accordance with ISO/IEC 17025. This CRM is traceable to SI unit kg and measured against primary material from a National Metrology Institute (NMI), e.g. NIST.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

Download your certificate at to view certified values, including uncertainty, date of expiry, and detailed information about trace impurities.


The phosphorus ICP standard may be used as following:
  • Estimation of metals and phosphorus in vegetable seeds by ICP-OES and ICP-MS
  • Inductively coupled plasma quadrupole-based mass spectrometry (ICP-QMS) based quantification of phosphorus in protein samples
  • Development and validation of an inductively coupled plasma -optical emission spectroscopy (ICP-OES) method for the determination of rare earth elements, thorium, yttrium, and phosphorus in monazite samples
  • Comparative analysis of inductively coupled plasma-mass spectrometry (ICP-MS) and colorimetry for the determination of total and extractable phosphorus in soils
  • Electrochemical measurement of dissolved phosphorus in canal water samples
  • Determination of phosphorus and potassium content of commercial inorganic fertilizers by ICP-OES
