The potential of microcolumn liquid chromatography (μLC) and capillary electrophoresis (CE) with on-line, flame photometric detection (FPD)in the P-selective mode has been studied for determination of polar P-containing pesticides, glyphosate and its main metabolite, aminomethylphosphonic acid (AMPA), ethephon, fosetyl-aluminium and acephate. Acephate was determined by reversed-phase μLC-FPD using large-volume injections with peak compression, the other compounds were determined by μLC-FPD and CE-FPD using simple, large-volume injection procedures to obtain limits of detection of 7.5-500 ng · mL-1 and 1.0 μg · mL-1, respectively. The methods showed acceptable repeatability and robustness and were successfully applied for rapid and selective determination of pesticides in fruit, vegetable and water samples.
