# Commission Regulation (EC) No 152/2009 of 27 January 2009 laying down the methods of sampling and analysis for the official control of feed (Text with EEA relevance), Division 6.2: Premixtures

Extent: E+W+S+N.I.

The diclazuril content w (mg/kg) in the sample is given by the following formula:
w=hd,s×hi,chi,s×hd,c×cd,c×0,02V×pm [mg/kg]
where:
hd,c peak height (area) of diclazuril in the calibration solution (3.10)
hi,c peak height (area) of the internal standard in the calibration solution (3.10)
hd,s peak height (area) of diclazuril in the sample solution (5.2.2)
hi,s peak height (area) of the internal standard in the sample solution (5.2.2)
cd,c diclazuril concentration in the calibration solution in μg/ml (3.10)
mweight of the test portion in g
Vvolume of the sample extract according to 5.2.2 (i.e. 25 ml)
pnominal content of diclazuril in mg/kg in the premixture
