快速催化性能监测-MKS MultiGas 2030 HS

CUSTOMER CHALLENGES： 1.Reducing catalyst performance testing time； 2. Reducing development time and costs； 3. Maintenance of multiple analytical instruments； 4. Accurate measurement of low level NOx； 5. Speciation of gas components directly without gas conditioning... BACKGROUND Currently, new catalyst performance evaluations require numerous analytical instruments to measure all species at varying load levels. These analyzers are expensive, costly and time-consuming to maintain, and for many, require extensive sample conditioning. For example, most analyzers require that the moisture level be very low for the instrument to work properly. This sample conditioning has been shown to provide systematic errors in NOx measurements. Also some gases such as NH3 cannot be measured directly. In this case NH3 is converted to NOx and then analyzed which adds even more complexity and greater potential for systematic error.
