title: [Separation and quantitative "in situ"-determination of organotin compounds on thin layer plates].
abstract: Residues of organotin compounds in feed and food are extracted with isopropanol. Clean up by means of a Sephadex LH-20 column and separation of the compounds of Kieselgel-G thin layer plates by 4-methyl-pentanone (2)/pyridine/acetic acid (97.5 + 1.5 +1) is achieved. Triphenyl- and tricyclohexyltin fungicides are quantitatively determined by direct scanning the thin layer plates using a chromatogram spectralphotometer.
