Blanks in method validation

A Supplement to the Eurachem Guide "The Fitness for Purpose of
Analytical Methods"


Cover of 'blanks' supplementBlanks are an important tool and are used in the determination of most performance characteristics during a validation process. They are also often included in each analytical run during routine use of the measurement procedure. There are many different types of blanks and the analyst must consider which blanks to include during preparation of the validation plan.

The aim of this supplement is to describe the different types of blanks which may be used during method validation and to provide guidance for situations where it may be difficult to obtain a suitable blank matrix. It is intended to be used in conjunction with "The Fitness for Purpose of Analytical Methods - A Laboratory Guide to Method Validation and Related Topics (2nd ed.)"
