title: Determination of diphenyltin and dialkyltin homologues by HPLC with morin in the eluent.
abstract: A sensitive and selective method has been developed for the simultaneous determination of diphenyltin and dialkyltin compounds. The compounds were separated by HPLC on a cyanopropyl-bonded silica column with toluene containing 1-5% acetic acid, 1-5% ethanol or methanol and 0.0015% morin. The organotins were eluted as morin complexes and detected by a fluorescence spectrophotometer. Detection limits ranged from 1 to 4 pg. Data reported include capacity factors, separation efficiencies and linearity of detection.
