 For the quantification of methionine in feed additive:
— ISO/CD 17180: ion exchange chromatography method with post-column derivatisation and photometric or fluorometric detection.
 For the quantification of total zinc in the feed additive and premixtures:
— EN 15510: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES), or
— CEN/TS 15621: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES) after pressure digestion.
 For the quantification of total zinc in the feedingstuffs:
— Commission Regulation (EC) No 152/2009 — Atomic Absorption Spectrometry (AAS), or
— EN 15510: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES), or
— CEN/TS 15621: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES) after pressure digestion. All species —  Pets: 250 (total)Fish: 200 (total)Other species: 150 (total)Complete and complementary milk replacers: 200 (total) 
1.. The additive shall be incorporated into the feed in form of a premixture.
2.. For user safety: breathing protection, safety glasses and gloves should be worn during handling.
