Determination of organotins in water by micro liquid chromatography-electrospray/ion trap mass spectrometry

Due to the varying toxicity the species of organotins in their widespread a pplications, it is important for analytical methods to address their specia tion. Traditional methods call for the hydrolysis and subsequent derivatiza tion of the organotins before analysis. These methods can be time-consuming , derivatization can be incomplete and high levels of background interferen ce produce difficulties in identification and quantification. The use is de scribed of a non-derivatization and non-hydrolysis micro-liquid chromatogra phy-electrospray/ion trap mass spectrometry for separation and detection of the organotins.
