With ever-growing public awareness of environmental quality and Canada's drive for environmental stewardship, research into mitigating air pollution and developing alternative sources of fuels are critical. The proposed capillary-inlet mass spectrometer will be applied to several projects focusing on reducing gaseous emissions from current and new hybrid automobiles and designing and developing new catalysts for hydrogen production. Its acquisition demonstrates a commitment to the growing need for research and development of technologies that result in improved air quality and alternative fuel research. For example, future emissions reductions from automobiles, both gasoline and diesel, require advanced, catalytic aftertreatment technologies and engine controls that account for catalyst performance trends. In order to design and maximize the efficiency of the catalysts, fast analysis of transient concentration changes of many varied species within the catalyst itself is needed. Hydrogen production from most sources require catalysts and these catalyst beds contain severe gradients. In order to design and optimize the catalysts and their distribution in a reactor, concentration gradients and degradation modes need to be determined. The proposed instrument/technique can run at the necessary frequency of data accumulation, and acquire data within the catalyst bed and reactor systems resulting in more complete analysis, for these new catalyst and reactor emission-controlling technologies. The mass spectrometer was chosen over other instruments due to its high data acquisition speed, ability to measure hydrogen and flexibility in probe location. The success of these programs and the training of the HQP involved will stimulate economic development and result in improved air quality in Canada as well as diversification of fuels for growing transportation and power requirements.

随着公众对环境质量的认识不断提高以及加拿大对环境管理的推动，对减轻空气污染和开发替代燃料来源的研究至关重要。拟议的毛细管入口质谱仪将应用于几个项目，重点是减少当前和新的混合动力汽车的气体排放，并设计和开发新的制氢催化剂。它的收购表明了对技术研发日益增长的需求的承诺，这些技术可以改善空气质量和替代燃料研究。例如，未来汽车（汽油和柴油）的排放减少需要先进的催化后处理技术和发动机控制，以适应催化剂性能趋势。为了设计和最大化催化剂的效率，需要快速分析催化剂本身内许多不同物质的瞬时浓度变化。大多数来源的氢气生产需要催化剂，这些催化剂床包含严重的梯度。为了设计和优化催化剂及其在反应器中的分布，需要确定浓度梯度和降解模式。所提出的仪器/技术可以以数据积累的必要频率运行，并在催化剂床和反应器系统内获取数据，从而对这些新的催化剂和反应器排放控制技术进行更完整的分析。质谱仪因其高数据采集速度、测量氢的能力和探针位置的灵活性而优于其他仪器。这些计划的成功和对相关HQP的培训将刺激经济发展，改善加拿大的空气质量，并使燃料多样化，以满足日益增长的运输和电力需求。
