A simple and rapid method using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) for direct multi-element analysis of wine samples without any sample pretreatment is described. Bestowed with its micro-sample consumption, the proposed method offers advantages of direct multi-element analysis in wine samples with high ethanol (1–20%) and salt contents, insignificant carbon deposits, reduced matrix effects, and better analytical performance. External calibration using either the solid reference material NIST 610 glass or aqueous standard solutions in combination with an indium internal standard provides accurate results. This calibration strategy offers a solution to the lack of a multi-element certified wine reference material for matrix-matched calibration. Twenty elements (Li, B, Mg, Al, V, Mn, Co, Cu, Zn, Rb, Sr, Y, Cs, Ba, La, Ce, Pr, Nd, Pb, and U) were determined in the wine samples. The proposed method was validated by a comparison with the conventional solution nebulization ICPMS method, with satisfying results. The detection limits for these elements were 0.01–1 ng mL⁻¹. The proposed method also has great potential for multi-element analysis in other beverages.

通过激光烧蚀ICPMS直接快速分析自然状态下的葡萄酒样品

描述了一种简单快速的方法，使用激光烧蚀电感耦合等离子体质谱法（LA-ICPMS）直接对葡萄酒样品进行多元素分析，而无需任何样品预处理。由于微量样品的消耗，该方法在乙醇含量高（1–20％）和含盐量高的葡萄酒样品中具有直接多元素分析的优势，碳沉积量微不足道，基质效应降低，并且分析性能更好。使用固态参考材料NIST 610玻璃或标准水溶液与铟内标结合进行外部校准可提供准确的结果。这种校准策略为缺乏适用于基质匹配校准的多元素认证葡萄酒参考材料提供了解决方案。二十种元素（Li，B，Mg，Al，V，Mn，Co，Cu，Zn，Rb，Sr，Y，Cs，Ba，在葡萄酒样品中确定了La，Ce，Pr，Nd，Pb和U）。通过与常规溶液雾化ICPMS方法的比较验证了该方法的有效性。这些元素的检出限为0.01–1 ng mL^-1。所提出的方法还具有在其他饮料中进行多元素分析的巨大潜力。
