Choose your Reference material

Reference Materials (RMs) are also available from Fapas for some analyte/matrix combinations. RMs have a much higher degree of characterisation than PT or QC materials with a defined chain of traceability. RMs undergo formal stability testing for both short-term and long-term applications. RMs have an associated datasheet which lists the reference values and their expanded uncertainty U. The value of U is not a performance limit but is the uncertainty relating to the reference value. RMs therefore have a greater degree of trust in their values and can be used for method calibration purposes. Fapas RMs are generated according to the principles of ISO Guide 17034:2016 General requirements for the competence of reference material producers.

Uses and properties of Reference Material (RM) samples
  • Provides a measure of accuracy
  • Reference values provided with uncertainty limits, independently of laboratory performance
  • Can be used for method validation or verification
  • Have a high degree of trust, enhancing confidence
  • Can be used to troubleshoot PT performance, generate control charts and for staff training
  • Stability fully characterised for long-term availability
  • Can be used for calibration purposes, including value assignment to other materials
  • Available only once fully characterised
  • CRMs have a defined traceability, which is also a characteristic of Fapas RMs.
