Division 6.2 Premixtures

United Kingdom

The diclazuril content w (mg/kg) in the sample is given by the following formula:

$w = \frac{h_{d,s} \times h_{i,c}}{h_{i,s} \times h_{d,c}} \times \frac{c_{d,c} \times 0,02V \times p}{m}$ [mg/kg]

where:

h_d,c

peak height (area) of diclazuril in the calibration solution (3.10)

h_i,c

peak height (area) of the internal standard in the calibration solution (3.10)

h_d,s

peak height (area) of diclazuril in the sample solution (5.2.2)

h_i,s

peak height (area) of the internal standard in the sample solution (5.2.2)

c_d,c

diclazuril concentration in the calibration solution in μg/ml (3.10)

weight of the test portion in g

volume of the sample extract according to 5.2.2 (i.e. 25 ml)

nominal content of diclazuril in mg/kg in the premixture
