Instrumentation for spatially and temporally resolved gas analysis

随着公众对环境质量意识的不断提高和加拿大对环境管理的推动，研究减轻空气污染和开发替代燃料来源至关重要。拟议的毛细管进口质谱仪将应用于几个项目，重点是减少现有和新的混合动力汽车的气体排放，以及设计和开发新的氢气生产催化剂。该公司的收购表明，该公司致力于改善空气质量和替代燃料研究的技术研发需求。例如，未来汽车的减排，无论是汽油还是柴油，都需要先进的催化后处理技术和发动机控制，这些都能反映催化剂性能的趋势。为了设计和最大限度地提高催化剂的效率，需要快速分析催化剂内部许多不同物种的瞬态浓度变化。从大多数来源制氢需要催化剂，这些催化剂床含有严重的梯度。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/技术可以在必要的数据积累频率下运行，并在催化剂床和反应器系统中获取数据，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。由于质谱仪的数据采集速度快，测量氢气的能力和探针位置的灵活性，因此选择质谱仪而不是其他仪器。这些项目的成功和对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，以满足日益增长的交通和电力需求。

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.
