Abstract Derivatization of tributyltin for tandem mass spectrometry is described. Tributyltin (TBT) and triphenyltin (TPT) were derivatized with sodium tetrakis(4-fluorophenyl)borate. After optimization of their MS/MS conditions, derivatization conditions were examined. Under the optimum conditions using in-situ derivatization, the calibration curves for the TBT and TPT were linear in the ranges of 0.4 - 200 and 1.2 - 200 pg of Sn, respectively. The detection limits for TBT and TPT were 0.07 and 0.43 pg of Sn, respectively. In the case of TBT, the detection limit with 4-fluorophenylation was improved about five times compared with that with pentylation (0.35 pg). This improvement is ascribed to the bonddissociation energy of Sn-aryl being stronger than that of Sn-alkyl. Namely, the selective fragmentation of 4-fluorophenyl TBT resulted in high sensitivity. The relative recoveries of TBT and TPT from seawater were 99 and 109%, respectively. The method was successfully applied to the seawater samples.
