摘要：

A single short (20 mm x 4 mm I.D.) column packed with C-18-bonded silica is used for both trace enrichment and liquid chromatographic (LC) separation of organic micropollutants in aqueous samples. The column can be used for at least twenty real-life samples without any decrease of performance. On-line short-column LC-diode array UV detection enables the detection of down to about 1 mu g/l of organophosphorus and other polar pesticides in surface water, using 15-ml samples. The total time of analysis is ca. 25 min. Preliminary results are shown for short-column LC-particle beam mass spectrometry.
