Outline of method
A known quantity of the capsule suspension is transferred to a glass bottle and is then subjected to a rolling movement with a specified amount of hexane containing an internal standard. After rolling for a specified period the amount of free pirimiphos-methyl in the hexane layer is determined by capillary gas chromatography.
