We propose to purchase an inductively-coupled plasma-mass spectrometer (ICP-MS). An ICP-MS is an analytical instrument that can determine many elements at low concentrations, below one microgram per litre (1 ppb). We currently have a 14 yr-old Agilent HP4500 ICP-MS. Since installation in 1997, it has been widely used by many researchers and students from the University of Ottawa and Carleton University; over 60 students in the last 6 yrs alone. The instrument has started to show aging, with unstable plasma signals; the manufacturer no longer supports the instrument and does not supply parts. More importantly, many of our projects require an ICP-MS with better capabilities, such as the reducion of interfering molecules, a better tolerance for salts and organic solvents. The new ICP-MS has these improved analytical capabilities to conduct projects listed below.

我们建议购买电感耦合等离子体质谱仪（ICP-MS）。ICP-MS是一种分析仪器，可以在低于1微克/升（1 ppb）的低浓度下测定许多元素。我们目前有一台14年历史的Agilent HP 4500 ICP-MS。自1997年安装以来，它已被渥太华大学和卡尔顿大学的许多研究人员和学生广泛使用;仅在过去的6年中就有60多名学生使用。仪器已开始老化，等离子体信号不稳定;制造商不再支持仪器，也不提供部件。更重要的是，我们的许多项目需要ICP-MS具有更好的功能，例如减少干扰分子，对盐和有机溶剂有更好的耐受性。新的ICP-MS具有这些改进的分析能力，可以进行以下项目。
