What Is an Analytical Reference Material?
Learn how well-characterized reference materials support analytical testing, method validation and comparison in laboratory quality systems.

Analytical measurements are more meaningful when laboratories have a reliable basis for comparison. Reference materials help provide that basis.
What is a reference material?
In general, a reference material is a sufficiently characterized material used for purposes such as comparison, calibration, system suitability or analytical method development and validation.
The exact role depends on the analytical procedure.
Why characterization matters
A useful reference material needs documented characteristics appropriate to its intended use—for example, identity, purity or another relevant property.
How might reference materials be used?
Depending on the analytical method, they may help laboratories:
- compare analytical responses
- establish or verify method performance
- support identification procedures
- evaluate system suitability
- validate analytical procedures
They should not be described simply as something that “calibrates HPLC” because their role can be much broader and method-specific.
Key Takeaway
A reference material provides a characterized point of comparison. Its suitability depends on what is known about it and how it is intended to be used.
