Division 2.2 Requirements
United Kingdom
Without prejudice to Article 11 of Regulation (EC) No 882/2004, the validated method for identification and characterisation to be selected by the laboratory shall comply with the quality criteria indicated in Tables 1 and 2.
Table 1
Quality criteria for methods for identification and quantification of chemical constituents in the solvent free mass and the volatile fraction of primary products
| Parameter | Value/Comment |
|---|---|
| Solvent free mass | At least 50 % by mass shall be identified and quantified |
| Volatile fraction | At least 80 % by mass shall be identified and quantified |
