| Abstract: | Tandem-in-space and tandem-in-time mass spectrometry is introduced with regard to its principle, structure and characteristics. Details of ionization, mother ion election, collision induced dissociation (CID) and ion ejection/detection are described. Application of ion trap tandem mass spectrometry in environmental analysis is reviewed in terms of detection of dioxin, PCBs, PAHs, pesticide residues and environmental hormones. |
