Inductively Coupled Plasma - Optical Emission Spectroscopy System

所要求的设备是安捷伦科技公司的AGILENT 5800电感耦合等离子体光学发射光谱仪（ICP-OES）。该仪器采用最可靠、最灵敏的方法，可在混合、复杂的水溶液和有机溶液中快速、同时测定痕量水平（百万分之一至十亿分之一范围）的多元素。ICP-OES的先进分析能力允许高度灵活性和多功能性使用，涵盖有机和水基液体基质的大检测限（从十亿分之一到百万分之数百）。它是一个标准的仪器元素分析（所有金属和类金属，如P， S和Si）在实验室与溶解元素在水和/或有机溶液中工作。ICP-OES可以分析任何类型的可溶解或可消化（即变为液体形式）的样品，因为该技术涵盖了各种应用领域，包括环境，地球化学，半导体，临床，核，化学，食品和冶金。多伦多大学化学工程系的各个研究小组专注于为金属/矿物、水回收、化学和纸浆和造纸工业开发新的可持续工艺和对环境负责的解决方案。正在进行的和计划中的研究项目涵盖了本系的广泛领域，共有6个小组，约有30名研究人员。因此，内部使用快速灵敏的同时多元素检测技术将极大地提高我们的生产力和分析精度。该部门目前的ICP-OES （Agilent 700系列，2010年生产）是通过NSERC RTI拨款（2011-2012申请期）购买的，它已经老化，接近制造商支持期的结束。虽然目前的维护和支持平均每年花费我们13000美元，但我们被告知“由于使用年限的原因，这种特殊型号的仪器现在已经不在保证支持范围内，而且维修部件的可用性有限”。这是我们持续研究工作的重要工具。我们完全依赖ICP-OES，需要在内部拥有一台全天候运行的仪器。在仪器故障/不可用的情况下，研究人员和学生将不得不求助于在部门外使用ICP-OES，这就提出了快速获取的问题，这是样品在较长时间内不稳定的一个重要因素（例如，样品成分可能因沉淀、生物活性或延长储存后的相变而改变）。此外，在部门配备ICP-OES仪器可确保正确的使用监督，维护的一致性，从而确保对测量和结果的信心。收购拟议中的新设备将使我们能够保持我们的研究质量目标，并使我们正在开发的新技术更接近商业化。

The requested equipment is the AGILENT 5800 Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) from Agilent Technologies. This instrument is using the most reliable and sensitive method for rapid, simultaneous multi-element determinations at trace level (part per million to part per billion range) in mixed, complex aqueous and organic solutions. The advanced analytical capabilities of the ICP-OES allow for high flexibility and versatility of use, covering large detection limits (from parts per billion to hundreds of parts per million) in both organic and aqueous-based liquid matrices. It is a standard instrument for elemental analysis (all metals and metalloids such as P, S and Si) in laboratories working with dissolved elements in aqueous and/or organic solutions. Any type of sample that can be dissolved or digested (i.e., brought into a liquid form) can be analyzed by ICP-OES, as the technique covers a diverse range of application areas including environmental, geochemical, semiconductor, clinical, nuclear, chemical, food, and metallurgical. Various research groups in the Chemical Engineering Department at the University of Toronto focus on developing novel sustainable processes and environmentally responsible solutions for the metals/minerals, water recovery, chemical and pulp and paper industries. Ongoing and planned research projects cover wide fields of interest in our Department among 6 groups employing about 30 researchers. As such, in-house use of a fast and sensitive simultaneous multi-element detection technique will elevate our productivity and analytical precision immensely. The present ICP-OES in the department (Agilent 700 series, manufactured in 2010) was purchased through an NSERC RTI grant (2011-2012 application period) is ageing and is nearing end of manufacturer's support period. Although current maintenance and support costs us $13,000/year on average, we have been advised that "this particular model of instrument is now out of guaranteed support due to age, and availability of repair parts is limited". This is an essential instrument for our continuing research efforts. We rely on ICP-OES entirely and need to have a functioning instrument in house 24/7. In case of instrument failure/unavailability, research staff and students will have to resort to ICP-OES use outside the Department, which raises the issue of prompt accessibility, an important factor for samples that are unstable over longer periods of time (for example, sample composition may alter due to precipitation, biological activity, or phase change upon extended storage). Moreover, having an ICP-OES instrument in the department ensures proper usage supervision, consistency in maintenance, and thus confidence in measurements and results. The acquisition of the proposed new equipment will enable us to maintain our research quality objectives and move one step closer to commercializing the new technologies that we are developing.
