The method of ionization by aerodynamic droplet breakup is considered for applications in mass spectrometric analysis. It is assumed that Aerodynamic Breakup Droplet Ionization (ABDI) occurs in a tube linking the region of atmospheric pressure to the area of weak vacuum. The possibility of ionization of solutions of organic compounds and organometallic complexes is shown. As test compounds were chosen: heroin (as an example of organic compounds) and organometallic complexes of ruthenium and copper, dissolved in water or acetonitrile. The quality of the ABDI spectra depends on the analyte. In general, the analytes ionized by the ABDI method show a great propensity to form dimers and trimers. ABDI system can be easily installed on any mass spectrometer with inlet at atmospheric pressure and used as an additional method. Since compounds prone to degradation in ESI analysis are better suited for ABDI analysis, this seems useful.

气动液滴破碎在质谱分析中的应用

考虑通过空气动力学液滴破碎的电离方法用于质谱分析。假定在将大气压区域与弱真空区域连接起来的管中发生了气动破裂液滴电离(ABDI)。显示了有机化合物和有机金属配合物溶液电离的可能性。选择测试化合物:海洛因(作为有机化合物的一个例子)以及溶于水或乙腈的钌和铜的有机金属络合物。ABDI光谱的质量取决于分析物。通常,通过ABDI方法电离的分析物显示出形成二聚体和三聚体的强烈倾向。ABDI系统可以很容易地安装在任何具有大气压入口的质谱仪上,并可以用作其他方法。
