A flexible carbon analysis platform

这项赠款申请是为了更换和扩大我们目前的碳分析设施，包括来自OI.Analytic的两个旧的TIC/TOC分析仪。这款车型已经停产5年了，不再有替换部件可用，也不再生产。去年8月，一台仪器出现故障，无法修复，而第二台仪器运行的部件是从更老的仪器上回收的，由该公司提供。这种情况极大地危及以碳动力学为中心的两个强大的现有研究项目(Del Giorgio和Prairie)和一个新兴的项目，届时新的教员德里将开始她的职位(2010年12月)。我们需要两种不同的碳分析仪器来扩展我们设施的能力。其中一个仪器是OI.Analyticals最先进的模型。这确保了与现有平台的连续性，但该仪器也能够分析固体样品(特别是沉积物样品和浓缩生物材料(例如浮游动物))的碳含量。要求的第二台仪器是Siever碳分析仪(5310C型)，它提供高通量、无与伦比的稳定性和精确度，以及便携性(不需要载气，使用预包装试剂)。然而，这台仪器不能做固体样品。所要求的平台将满足我们至少在未来十年的碳分析需求。

This grant request is to replace and expand our current carbon analysis facility consisting of two old TIC/TOC analyzers from O.I. Analytical. This model has been out of production for 5 years and replacement parts are no longer available or manufactured. One instrument has failed last August and cannot be fixed while the second instrument runs on parts scavenged from even older instruments and supplied by the company. This situation greatly jeopardizes two strong existing research programs that are centred on carbon dynamics (del Giorgio and Prairie) and an emerging program when new Faculty member Derry will begin her position (Dec. 2010). We request two different carbon analysis instruments to expand the capabilities of our facilities. One of the instrument is the state-of-the-art model from O.I. Analyticals. This ensures continuity with existing platform but this instrument is also capable of analyzing the carbon content of solid samples (in particular sediment samples and concentrated biological material (e.g. zooplankton). The second instrument requested is a Siever carbon analyzer (model 5310C) that offers high throughput, unsurpassed stability and precision, and portability (doesn't require carrier gas and uses pre-packaged reagents). However, this instrument cannot do solid samples. The requested platform will meet our carbon analysis needs for at least the coming decade.
