Based on their behavior as stable cations in saline solutions, direct trace speciation of a broad range of organotins, representing current industrial or environmental interests, was performed by combination of an tin-specific graphite furnace atomic detector with HPLC employing reverse bonded-phase strong cations exchange columns. Column and system performance and detection limits 5-30 ng as tin vary predictably with individual substituents on organotins, but are easily optimized, for example, for identifying marine antifoulant leachates.
