开展金属材料的直接质谱分析，不仅有助于提高金属材料分析速度、检测灵敏度以及准确度，同时对拓展直接质谱技术在金属领域的应用具有重要意义。本项目在既往工作基础上，结合电化学电解技术和质谱分析技术，拟研制一种电化学-质谱联用装置，并基于此实验装置，开展金属材料直接质谱分析研究。项目将对实验装置和实验参数（如电解质溶液、电解电压、雾化气压力、电离电压等）进行系统的研究，探索作用机理，总结作用规律，最终建立一种无需样品前处理、样品消耗量小、简单快速、准确灵敏的金属材料直接分析方法。本研究不仅有望解决直接质谱分析方法在金属直接电离中的技术难题，拓展直接质谱技术在金属领域的应用，同时为金属材料快速分析提供了一种新方法。

Rapid and accuracy analysis of metallic materials by ambient mass spectrometry not only improves the speed, sensitivity and accuracy of metallic analysis but also has great significance in the applying of ambient mass spectrometry in metallic materials analysis. Based on our previous works, we will develop an electrolytic cell coupled with mass spectrometry device for metallic materials analysis. The parameters of experimental and device, such as electrolyte, potential, atomizing gas pressure and ionization voltage will be systematic investigated to construct a rapid, accuracy and small sample consuming method for direct analysis of metallic materials without sample pretreatments. This method will provide a powerful tool for improving processing technology, and developing new ambient mass spectrometry method for metallic materials analysis. Meanwhile, this study will pave a way for direct analysis of metallic materials by ambient mass spectrometry.
