Transfer of published methods into a single laboratory

2 Transfer of published methods into a single laboratory 

The Nordic Committee on Food Analysis has published a guideline on the Validation of Chemical Analytical Methods which differentiates between external validation work carried out on published methods and that work required to transfer it into the working laboratory to confirm its suitability for use. Table 20 is adapted from this document. This document is most easily accessed from a recently published book If certified reference materials are available they should be used to confirm the verification of trueness. These guidelines could also apply to intra-laboratory training programmes. 

The overall validation requirements given in the guideline of the Nordic Committee on Food Analysis on the Validation of Chemical Analytical Methods 5 are listed in Table 12. 

The method is externally validated in a method-performance study 

The method is externally validated in a method-performance study but is to be used with a new sample matrix or using new instruments
