The positive ion electrospray mass spectra of the quatemary ammonium salt herbicides paraquat and diquat are examined by on-line separation with capillary electrophoresis (CE) and by direct infusion of the analytes. The analytes are separated by CE in 7-10 min at pH 3.9 in 50% methanol-water by usin
Capillary electrophoresis CE and mass spectrometry MS were investigated for the analysis of paraquat and diquat herbicides. The mass spectrometer ลฝ . was a home-built time-of-flight instrument TOFMS equipped with an electro-ลฝ . spray ionization ESI source. A coaxial liquid sheath ESI source was util
Capillary electrophoresis (CE) has been used for the characterization of the herbicides mepiquat, chlormequat, diquat (DQ), paraquat (PQ) and difenzoquat. A volatile running electrolyte solution containing acetic acidammonium acetate 50 mM (pH 4) with 10% of methanol as modifier was used to reduce a
