In order to identify the common metal ions in the base Baijiu of Sanpaijing process (BBSP) and their migration rules during brewing, the traditional and mechanized productions of BBSP were studied by inductively coupled plasma mass spectrometry-combined with matrix matching and direct sampling. The wet digestion method was applied to determine the content change of common metals ions in traditional BBSP. The results showed that the content of metal ions in mechanized BBSP was lowest, which was about 7.95%-20.24% of that in the traditional BBSP. Whereas, among the three traditional BBSP, the content of total common metal ions in the ordinary one and extended-fermented one was higher than that in the middle-fractioned one. In the distillation process, very trace portion of the common metal ions was shifted from the fermented grains to the base Baijiu with a shifting rate of 0.0070%-0.0078% and most portion of the common metal ions remained in the vinasse during brewing due to their non-volatility.
