Five polar herbicides were separated and characterised using high‐speed analytical countercurrent chromatography (HSACCC) in conjunction with online electrospray mass spectrometry (ESI‐MS). The countercurrent chromatography used a standard isocratic biphasic solvent system of hexane/ethyl acetate/methanol/water in reverse phase to effect the separation of these five environmentally important compounds. The chromatograph was coupled to a triple quadrupole mass spectrometer via a standard electrospray liquid chromatography interface that was able to give mass spectra in negative ion mode of each compound. Limits of detection are reported for this series of compounds along with representative negative ion ESI‐MS data and calibrations for the separation. Copyright © 2001 John Wiley & Sons, Ltd.
