Abstract
On-line coupling continuous-flow liquid membrane extraction (CFLME) with HPLC, a novel automatic system was developed for the determination of sulfonylurea herbicides in water. After an automatic trace-enrichment process by CFLME, which is the combination of continuous flow liquid-liquid extraction and support liquid membrane (SLM) extraction, the target analytes were concentrated in 50 microl of 0.2 M Na2CO3-NaHCO3 (pH 10.0) buffer. The concentrated sample solutions were injected directly onto a C18 analytical column with a valve, and detected at 240 nm with a diode array detector. Metsulfuron methyl (MSM), and DPX-A 7881 were baseline separated with a mobile phase consisting of methanol and 67 mM KH2PO4-Na2HPO4 (pH 5.91) buffer (45+55, v+v) at a flow-rate of 1.0 ml min(-1). With an enrichment time of 10 min and enrichment sample volume of 20 ml, the enrichment factors and detection limits are 100 and 0.05 microg l(-1) for MSM, and 96 and 0.1 microg l(-1) for DPX-A 7881, respectively. The linear range and precision (RSD) are 0.1-50 microg l(-1) and 7.0% for MSM, and 0.2-50 microg l(-1) and 9.2% for DPX-A 7881, respectively. This proposed method was applied to determine MSM and DPX-A 7881 in seawater, tap water, and bottled mineral water with spiked recoveries in the range of 83-95% for MSM and 88-100% for DPX-A 7881, respectively.

Abstract
The determination of pesticides in water is fundamental to the solution of environmental problems as natural waters are usually contaminated with a large number of pesticides. The selection of an isolation and/or concentration technique depends largely on the class of pesticides to be determined. It is often necessary to determine simultaneously a wide variety of compounds in a water sample. Application of solid-phase extraction techniques offers a solution. The mechanisms of solid-phase extraction, types of sorbents and their application to multi-residue pesticide analysis are reviewed.

Abstract
A technique for sample work-up and enrichment using a supported liquid membrane in an automated flow system, connected to a gas chromatograph, was used for the determination of aliphatic amines in human blood plasma. The amines studied were N,N-dimethylethylamine, triethylamine, N-methylmorpholine, cyclohexylamine and N,N-dimethylcyclohexylamine. An efficient clean-up of the complex plasma matrix was achieved, resulting in identical blank chromatograms for plasma samples and aqueous solutions. Different parameters influencing the efficiency and selectivity of the extraction procedure were experimentally studied and theoretically explained. The detection limit depends on the extraction flow-rate and the available sample volume. With 1 ml of sample and a flow-rate giving an extraction time of 16 min, the detection limit was ca. 5 ppb (5 micrograms/l); with 4 ml of sample and a lower flow-rate, sub-ppb detection limits could be reached in ca. 3 h. Linear calibration curves up to 500 ppb were obtained. Blood plasma samples from volunteers exposed to N,N-dimethylethylamine in air were analysed, and the results compared favourably with independent measurements by another method.
