Four distinct yet complementary research programs will be supported by the requested equipment, which will be used to upgrade our existing Organic Carbon Characterization System (OCCS). The upgrade is needed because some of the system components have reached their functional life and need replacement. The OCCS is essential to measure and comprehensively characterize the different fractions of the natural organic matter (NOM) in raw drinking water sources. Of particular interest is the molecular size distribution of the different NOM fractions and the detection and measurement of emerging contaminants of concern (e.g. pharmaceutical compounds) as well as algal toxins. A comparable OCCS is only available at one other institution in Canada (University of Waterloo). The existing OCCS is essentially in continuous use (24 hours per day, 5-7 days per week) by the supported programs. At any point in time, the research projects of over 10 HQP depends on the availability of the OCCS. Over the lifetime of the existing OCCS (i.e. over the past 20+ years), it is estimated that over 100 students have used and/or benefited from having access to the system. Without an upgrade, the OCCS will not be functional for much longer and the supported research programs will no longer be feasible.

所要求的设备将支持四个截然不同但相互补充的研究项目，这些设备将用于升级我们现有的有机碳表征系统(OCCS)。升级是必要的，因为一些系统组件已达到其功能寿命，需要更换。OCCS对于测量和综合表征饮用水源中天然有机物(NOM)的不同部分是必不可少的。特别令人感兴趣的是不同NOM组分的分子大小分布以及对新出现的令人关注的污染物(如药物化合物)以及藻类毒素的检测和测量。类似的OCCS只在加拿大的另一所机构(滑铁卢大学)提供。现有的OCCS基本上是由所支持的计划连续使用(每天24小时，每周5-7天)。在任何时候，超过10个总部基地的研究项目都取决于OCCS的可用性。在现有开放源码系统的使用期间(即过去20多年)，估计有超过100名学生使用和/或受益于该系统。如果不升级，OCCS将不会再起作用很长时间，所支持的研究计划也将不再可行。
