The Determination of Galaxolide in Water Samples with SPME Coupled with GC-MS
Described is a solid-phase microextraction-gas chromatography mass spectrometric procedure for the determination of galaxolide (HHCB) in water solution samples. In which 100 μm PDMS coated fiber were used. From the optimization experiments of SPME, we found the direct sampling is necessary. The extraction time and temperature were 40min and 35°C, respectively. the salinity of the solution almost has no effect on the extraction efficiency and pH=7.0 was suitable for the extraction of HHCB. The method were applied to the urban sewage and river water respectively and found the content of HHCB in the urban sewage is 286ng/L, while those in river water below limit of quantification.
