    • An assembly and method for gas analysis. The assembly comprises a catalyst compartment for catalytically reacting a component of a gas sample, producing one or more gas species as products. A product compartment receives the gas species, and a sensing element within the compartment senses the amount of one or more of the gas species. This amount is compared to the amount of the same gas species present in a reference compartment containing a non-catalyzed gas sample, providing the amount of the gas species produced by catalysis. Using this value, the content of the gas component in the gas sample is calculated based upon the stoichiometry of the catalyzed reaction. In preferred embodiments, the gas for analysis is a process gas for fuel production, and the catalyst is a high temperature shift catalyst that catalyzes the reaction of carbon monoxide and water into hydrogen and carbon dioxide.

    • An apparatus and method for gas detection. The apparatus comprises a) a sample chamber for holding a gas sample, b) a sealable vacuum port in fluid communication with the sample chamber, for evacuating the sample chamber, c) a sealable inlet port in fluid communication with the sample chamber, for introducing the gas sample into the evacuated sample chamber, and d) a thermal conductivity sensing element at least partly disposed within the sample chamber, for measuring the thermal conductivity of the gas sample. A gas sample released into the evacuated sample chamber requires a time interval to contact the thermal conductivity sensing element. The time interval is a measure of gas speed. Thermal conductivity and temperature of the gas sample are measured following determination of gas speed. By determining three parameters in a single sample of gas, different gas mixtures having similar thermal conductivities can be distinguished.
    • 一种用于气体检测的装置和方法。 该设备包括:a)用于保持气体样品的样品室,b)与样品室流体连通的可密封真空端口,用于抽空样品室; c)与样品室流体连通的可密封入口,用于引入 气体样品进入抽真空的样品室,以及d)至少部分地设置在样品室内的热传感元件,用于测量气体样品的热导率。 释放到抽空样品室中的气体样品需要与热敏感测元件接触的时间间隔。 时间间隔是气体速度的量度。 在确定气体速度后测量气体样品的导热系数和温度。 通过确定单个气体样品中的三个参数,可以区分具有相似热导率的不同气体混合物。
