Inductively Coupled Plasma - Optical Emission Spectroscopy System

所要求的设备是安捷伦技术公司生产的安捷伦5800电感耦合等离子体-光学发射光谱仪(ICP-OES)。该仪器使用最可靠和最灵敏的方法，在混合、复杂的水溶液和有机溶液中进行痕量水平(百万分之几到十亿分之一范围)的快速、同时多元素测定。电感耦合等离子体原子发射光谱仪的先进分析能力使其具有很高的灵活性和使用的多功能性，涵盖了有机和水基液体基质中较大的检测下限(从百万分之几到百万分之几百)。它是实验室中处理水和/或有机溶液中溶解元素的标准元素分析仪器(所有金属和类金属，如P、S和Si)。任何类型的可溶解或消化的样品(即，以液体形式带入)都可以通过电感耦合等离子体发射光谱仪进行分析，因为这项技术覆盖了环境、地球化学、半导体、临床、核、化学、食品和冶金等各种应用领域。多伦多大学化工系的多个研究小组致力于为金属/矿物、水回收、化工以及纸浆和造纸行业开发新的可持续工艺和对环境负责的解决方案。正在进行和计划中的研究项目涵盖了我司感兴趣的广泛领域，6个小组雇用了约30名研究人员。因此，内部使用快速和灵敏的同时多元素检测技术将极大地提高我们的生产率和分析精度。该部门目前的ICP-OES(安捷伦700系列，制造于2010年)是通过NSERC RTI赠款(2011-2012年申请期)购买的，正在老化，即将结束制造商的支持期限。虽然目前的维护和支持费用平均为13,000美元/年，但我们被告知，“这种特殊型号的仪器由于年代久远，现在已经没有了保证支持，维修部件的供应也很有限”。这是我们继续研究工作的重要工具。我们完全依赖ICP-OES，需要一台全天候正常工作的仪器。如果仪器发生故障/不可用，研究人员和学生将不得不求助于系外使用的ICP-OES，这带来了迅速获取的问题，这是长期不稳定的样品的一个重要因素(例如，样品的成分可能会因降水、生物活动或延长储存时间后的相变而改变)。此外，该部门拥有一台ICP-OES仪器，确保适当的使用监督、维护的一致性，从而确保对测量和结果的信心。收购拟议的新设备将使我们能够保持我们的研究质量目标，并朝着我们正在开发的新技术的商业化又迈进了一步。

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.
