| Abstract: | The organic compounds in redtide seawater were detected by solid-phase microextraction (SPME) coupled to gas chromatography mass spectrometry (GC-MS). SPME is a new solventless sample preparation method which could be compatible with high-speed separations. SPME offers a unique combination of sampling (from virtually all matrices) and sample introduction to the GC-MS by means of the same simple device. SPME-GC-MS method is particularly suitable for the detection of organic compounds in seawater matrices. The variations of organic compound concentration and species in redtide seawater were studied in detail. The reason of the variation were discussed briefly. It provided foundation for investigation of redtide mechanism and its prediction. |
