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.

Scope

The method is intended for use only with pirimiphos-methyl CS formulations for public health applications.
