X-ray photoelectron spectroscopy (XPS) is an essential surface analysis instrument that measures the binding energy of electrons emitted from the surfaces of samples when irradiated by X-rays. Since every element manifests unique electron binding energies, this technique is used to identify the atomic nature and the chemical bonding states in the near-surface region. The current XPS system was purchased in 2000 when the Electrochemical Technology Centre (ETC) at the University of Guelph was formed; it has been extensively used over the past 17 years. One challenge with the equipment is that the software is DOS-based. Once acquired, data must be exported via floppy disk to another computer where we have, over the years, run various freeware programs to conduct data analysis. In recent years, the system has become increasingly difficult to maintain. Some issues include water leaks in the cooling system, drifts, electronic instabilities, degraded sensitivity and resolution, and the simple difficulty of maintaining a DOS system when new computers are unable to interface with the existing electronics. This XPS system can no longer be pieced together to maintain functionality. The proposed XPS upgrade is urgently required to support a number of research programs funded by NSERC at the University of Guelph.

X射线光电子能谱（XPS）是一种重要的表面分析仪器，可测量样品表面受X射线照射时发射的电子的结合能。由于每种元素都表现出独特的电子结合能，因此该技术用于识别近表面区域的原子性质和化学键合状态。目前的 XPS 系统是在 2000 年圭尔夫大学电化学技术中心 (ETC) 成立时购买的；它在过去 17 年里得到了广泛的应用。该设备面临的一项挑战是该软件是基于 DOS 的。一旦获取，数据必须通过软盘导出到另一台计算机，多年来我们一直在该计算机上运行各种免费软件程序来进行数据分析。近年来，该系统变得越来越难以维护。一些问题包括冷却系统漏水、漂移、电子不稳定、灵敏度和分辨率下降，以及当新计算机无法与现有电子设备连接时维护 DOS 系统的简单困难。该 XPS 系统无法再拼凑在一起以维持功能。迫切需要拟议的 XPS 升级来支持圭尔夫大学 NSERC 资助的多项研究项目。
