| Abstract: | A method of gas chromatography mass spectrometry in the selected ion monitoring mode(GC-MS-SIM) with large volume injection was evaluated of trace DDT in tea sample. DDT was extracted from the sample with acetone and cleaned with sulphuric. The lowest detection limits of this method for DDT was 0.8μg/kg. |
