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.
