A method is described for the gas chromatographic determination of nanogram amounts of mono-, di- and tributyltin compounds and mono-, di- and triphenyltin compounds in biological and sediment samples. These compounds are converted into the corresponding chlorides with hydrochloric acid, extracted with ethyl acetate and hydrogenated with sodium tetrahydroborate. The corresponding hydrides, mono-n-butyltin hydride, di-n-butyltin hydride, tri-n-butyltin hydride, monophenyltin hydride, diphenyltin hydride triphenyltin hydride, are detected by electron-capture gas chromatography after clean-up by silica gel column chromatography. The detection limits are 10-20 ng/g for mono-n-butyltin chloride, 0.5-1 ng/g for di-n-butyltin chloride, 1-2 ng/g for tri-n-butyltin chloride and diphenyltin chloride and 2.5-5 ng/g for monophenyltin chloride and triphenyltin chloride, in biological and sediment samples.
描述了一种气相色谱法，用于测定生物和沉积物样品中纳克级的一丁基锡、二丁基锡和三丁基锡化合物以及一苯基锡、二苯基锡和三苯基锡化合物。这些化合物用盐酸转化为相应的氯化物，用乙酸乙酯萃取并用硼氢化钠氢化。通过硅胶柱色谱净化后，用电子捕获气相色谱法检测相应的氢化物，即一正丁基锡氢化物、二正丁基锡氢化物、三正丁基锡氢化物、一苯基锡氢化物、二苯基锡氢化物、三苯基锡氢化物。生物和沉积物样品中一正丁基氯化锡的检测限为10 - 20 ng/g，二正丁基氯化锡为0.5 - 1 ng/g，三正丁基氯化锡和二苯基氯化锡为1 - 2 ng/g，一苯基氯化锡和三苯基氯化锡为2.5 - 5 ng/g。
