MT 190.2 Determination of Release Properties of Pirimiphos-Methyl in CS Formulations
Content Handbook O
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 a hexane/ethanol mixture containing an internal standard. After rolling for 15 min, the amounts of pirimiphos-methyl in the solvent layer are determined by capillary gas chromatography.
The method is intended for use only with pirimiphos-methyl CS formulations for public health applications.
