Abstract The choice of an adequate nebulizer reflects directly in the accuracy, especially when a complex matrix is analyzed in plasma techniques. To unveil the effects on fundamental parameters and analytical performance of a microwave-induced plasma optical emission spectrometry, four commercial nebulizers, Concentric, Mira Mist, OneNeb series 1, and OneNeb series 2, were evaluated. Estimated fundamental plasma parameters, excitation temperature (T), and the number of electron density (ne) indicated that the Mira Mist nebulizer afforded a plasma with the highest T and ne, but the lowest solvent transport efficiency. OneNeb series 2 showed the lowest T and ne, nonetheless the highest solvent transport efficiency. The precision was estimated in the middle of nitric acid (1% v v-1), sulfuric acid (1% v v-1), easily ionizable elements (100 mg L-1 of Ba, K, and Na), ethanol (1% v v-1), and carbon content (1000 mg L-1). The OneNeb series 2 presented the lowest RSD and LOD values in all matrices, while the concentric presented the highest RSD. The accuracy was evaluated by certified reference materials and addition and recovery experiments performed in sugarcane spirit. Considering the sensitivity improvement, solvent transport efficiency and analytical precision the OneNeb series 2 achieved superior performance.

微波诱导等离子体发射光谱法对不同雾化器性能的评价

摘要 选择合适的雾化器直接影响精度，尤其是在等离子体技术中分析复杂基质时。为了揭示微波诱导等离子体发射光谱法对基本参数和分析性能的影响，对四种商用雾化器 Concentric、Mira Mist、OneNeb 系列 1 和 OneNeb 系列 2 进行了评估。估计的基本等离子体参数、激发温度 (T) 和电子密度数 (ne) 表明 Mira Mist 雾化器提供的等离子体具有最高的 T 和 ne，但溶剂传输效率最低。OneNeb 系列 2 显示出最低的 T 和 ne，但溶剂传输效率最高。在硝酸 (1% v-1)、硫酸 (1% v-1)、易电离元素（100 mg L-1 Ba、K 和 Na）、乙醇（1% v v-1）和碳含量（1000 mg L-1）。OneNeb 系列 2 在所有基质中呈现最低的 RSD 和 LOD 值，而同心的呈现最高的 RSD。通过经认证的标准物质以及在甘蔗酒中进行的添加和回收实验来评估准确性。考虑到灵敏度的提高、溶剂传输效率和分析精度，OneNeb 系列 2 实现了卓越的性能。
