Quantitation and Identification of Organotin Compounds in Food, Water, and Textiles Using LC-MS/MS

Organotin compounds are chemicals composed of tin linked to hydrocarbons, used in industrial materials and various biocides and fungicides. As a result, organotin compounds can enter the environment through a number of channels, and can often be found in seawater, seafood, fruits and vegetables, and consumer goods. Due to the toxicity of these compounds, there is a need for analytical methods allowing accurate quantitation and identification. Here we present an LC-MS/MS method to measure tributyltin, fentin, cyhexatin, and fenbutatin oxide in different matrices. Triphenyl phosphate was used as the internal standard.
