Good separation was achieved for each class of s-triazines as cations, except for the chlorotriazines, with buffer pH around the pKa of the herbicides, as well as at a pH of pKa − 2. Migration times were correlated with molecular masses (as a first approximation of molecular size and shape). Possible hydrophobic wall interactions were detected at acidic pH and low voltage. Separation of hydroxytriazine metabolites as anions could also be achieved at a high pH of around 8. The detection level calculated for most of these s-triazines was μg/ml of analyte in the injection solution.
