| Abstract: | The determination of carbamate and triazine pesticides from soil leachates and slurries was investigated using solid phase microextraction (SPME) coupled to high-performance liquid chromatography-electrospray/ mass spectrometry (HPLC-ESI/MS). SPME was carried out using fibres with a newly developed 50 μm Carbowax/ template coating which are suitable for relatively polar analytes. These fibers exhibit precisions better than 10% RSD, and are resistant against high contents of organic solvents during desorption. The technique shows a high sampling frequency resulting in an increasing sample throughput. Received: 17 December 1997 / Revised: 30 October 1998 / Accepted: 10 November 1998 |
