Objective To establish a method for rapid determination of 26 kinds of elements in liquor by inductively coupled plasma mass spectrometry (ICP-MS) adopting matrix matching. Methods Combining with kinetic energy discrimination (KED) and internal standard correction mode, the determination method of Cd, Sn, Ba, Pb, Li, B, Mg, Al, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, Mo, Sb, Na, Se and Hg in liquor had been established though direct dilution injection, and compared with the standard test method. Results The results showed that the correlation coefficient of standard curve was 0.9990-0.9999, the limit of determination was 0.1-300.0 μg/L, the standard recovery rates were 94.5%-104.4%, the relative standard deviations (RSDs) were 0.1%-1.2%. The standard recovery rate was obviously better than that without matrix matching method. The performance parameters of the method met the requirements of GB 5009.295—2023 National food safety standards-General rules for verification of chemical analysis methods. Compared with the standard test method, it could effectively reduce the pre-treatment steps, shorten the pre-treatment time, and save consumables. The results of the 2 kinds of methods showed no significant difference. Conclusion The method is simple, fast, accurate, stable and reliable, and is suitable for the bulk detection of multielement in liquor. The method provides technical support for ensuring liquor quality and safety.
