 Analytical method
 For the determination of hydroxy analogue of methionine in the feed additive:
— High performance liquid chromatography coupled to UV detection at 220 nm (HPLC-UV)
 For the determination of total selenium in the feed additive:
— Inductively coupled plasma mass spectrometry (ICPMS) after microwave digestion with HNO3/H2O2, or
— Inductively coupled plasma atomic emission spectrometry (ICPAES) after digestion with HNO3/HCl
 For the determination of total selenium in premixtures and feed:
— Hydride generation atomic absorption spectrometry (HGAAS) after microwave digestion with HNO3/H2O2 (EN 16159:2012) All species —  0,50 (total) 
1.. The additive shall be incorporated into feed in the form of a premixture.
2.. For user safety: breathing protection, safety glasses and gloves should be worn during handling.
3.. Maximum supplementation with organic selenium:
0,20 mg Se/kg of complete feed with a moisture content of 12 %. 4 June 2023
