# 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 the results

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

From the mean height (area) of the olaquindox 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 olaquindox content w in mg/kg of the sample is given by the following formula:
w=c ×1000min which:
colaquindox concentration of the sample extract (5.2) in μg/ml
mweight of the test portion in g (5.2).
