Outline of method

Tribenuron-methyl is determined by reversed phase high performance liquid chromatography using a 100 × 4.6 mm (i.d.) Whatman Partisil® ODS-3 RAC II column, UV detection at 254 nm and internal standardisation (3-methyl-1,1-diphenylurea; DPMU). The active ingredient content is quantified using a calibration curve.

Scope

The method is usable for TC and WG-formulations.
