Notes:
The organotins, mainly the trialkyltins and triphenyltins, have a widespread application as fungicides, anti-fouling coatings for porous and non-porous surfaces, herbicides, insecticides, and generic biocides. Traditional environmental monitoring methods can only give limited speciation of the organometallics. The speciation of a wide variety of alkyl- and aryl-tin isomers using liquid chromatography coupled with mass spectrometry under positive-ionization conditions is reported. Detection of the organotins was enhanced by the use of acetic acid in the methanol mobile phase. There were unexpected high-mass ions with multiple tin-isotope patterns present in many of the spectra. These high-mass species were possibly attributable to tin polymers, whose presence has been observed by others using X-ray methods.
