Outline of method
Metsulfuron-methyl is determined by high performance liquid chromatography on a reversed phase column (C8) using water - acetonitrile (65 + 35 v/v at pH 3) as eluent and UV detection at 254 nm. The content of active ingredient is quantitated using a calibration curve.
The method is usable for TC and WG-formulations.
