HPLC Analysis of Clopyralid

Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide effective against broad-leaf plants such as clovers and thistle. A single residue method for the EURL (European Union Reference Laboratory) was developed for clopyralid and other acidic compounds using QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methodology. Retention of clopyralid was controlled on both Obelisc R and a 3 micron Primesep 100 column of the same dimension. This method is LC/MS compatible and useful for separating many pesticides.
