Division 6 Calculation of the results
United Kingdom
From the mean height (area) of the amprolium peaks of the sample solution determine the concentration of the sample solution in μg/ml by reference to the calibration graph (5.3.2).
The amprolium content w in mg/kg of the sample is given by the following formula:
[mg/kg]
in which:
V c f m
volume of the extraction solvent (3.8) in ml according to 5.2 (i.e. 200 ml)
amprolium concentration of the sample extract (5.2) in μg/ml
dilution factor according to 5.2
weight of the test portion in g.
