# 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: Calculation of results

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

Determine the concentration of the sample solution in μg/ml, from the mean height (area) of the halofuginone peaks of the sample solution by reference to the calibration graph (5.4.2).
The content of halofuginone w (mg/kg) of the sample is given by the following formula:
w=c×10min which:
chalofuginone concentration of the sample solution in μg/ml,
mweight of the test portion in grams.
