Samples of margarines, butter and vegetable oils were analyzed for volatile N‐nitrosamines by the vacuum steam distillation method followed by dichloromethane extraction of the distillate and gas chromatographic‐thermal energy analysis (GC‐TEA) of the extracts. No volatile nitrosamines in excess of a practical limit of determination of 0.5 ppb were found in any of the samples. The problem of artifact formation during analysis of low levels of nitrosamines and the meaning of a “practical limit of determination” is briefly discussed.
