X射线光电子能谱（XPS），这本质上需要真空，被用来表征化学物种在液体中使用实验室XPS设备配备了传统的铝-钾α源和环境细胞与超薄氮化硅膜作为准透明窗口的X射线和光电子的传输。将不同浓度的氯化铯水溶液封装在电池中，用X射线照射与溶液接触的膜，以收集从液体中的化学物质发射的光电子。观察到铯4d光电子峰，峰强度随浓度成正比增加。因此，证明了该方法对溶液物种的定量分析。由AIP Publishing授权出版。
X-ray photoelectron spectroscopy (XPS), which intrinsically requires vacuum, was used to characterize chemical species in a liquid using laboratory XPS apparatus equipped with a conventional Al-K alpha source and an environmental cell with an ultra-thin silicon nitride membrane as a quasi-transparent window for the transmission of X-rays and photoelectrons. Aqueous solutions of cesium chloride at different concentrations were encapsulated in the cells, and the membrane in contact with the solution was irradiated with X-rays to collect the photoelectrons emitted from the chemical species in a liquid through the membrane. Cs 4d photoelectron peaks were observed, and the peak intensity increased proportionally with the concentration. Thus, the quantitative analysis of solution species by this method is demonstrated.
