摘要： A system is provided for analyzing the particles in aerosols, as in making air pollution studies, which enables the making of rapid chemical analyses of particles. The system includes an apparatus for producing a controlled stream of individual particles to be analyzed from an environment, and an apparatus for vaporizing and ionizing the particles while they move in free flight, for analysis by a mass spectrometer. The apparatus for producing a stream of particles includes a capillary tube through which the air with suspended particles moves, a skimmer device having a small opening spaced from an end of the capillary tube to receive particles passing through the tube, and a vacuum pump for pumping air out of the space between the tube and skimmer. The vacuum pump serves to remove much of the gas from around the particles, while also creating an inflow of air and particles through the capillary tube. The particles passing through the skimmer opening can be simultaneously vaporized and ionized while in free flight, by a laser beam of sufficient intensity that is directed across the path of the free flying particles.

摘要： Method for the online measurement of the number, surface area and volume distribution of nanoparticle aerosol aggregates relates the number and size of primary particles that compose the aggregates and the aggregate mobility diameter. The number distribution of nanoparticle aggregates is obtained by calculations based on the drag on the aggregates and the aggregate charging efficiency. The aggregate surface area and volume are obtained by summing over the surface areas and volume of the primary particles that compose the aggregate. The aggregate surface area and volume distribution is then obtained by multiplying the aggregate surface area, volume and the aggregate number distribution.
摘要翻译：在线测量纳米颗粒气溶胶聚集体的数量，表面积和体积分布的方法涉及构成聚集体的一次粒子的数量和尺寸以及聚集体迁移率直径。通过基于聚集体上的阻力和聚集体充电效率的计算获得纳米颗粒聚集体的数量分布。通过对构成聚集体的一次颗粒的表面积和体积进行求和来获得聚集体表面积和体积。然后通过将骨料表面积，体积和总数分布相乘获得骨料表面积和体积分布。

摘要： A catalytic reactor bed in which support particles in the free molecule size range of 50 to 500 .ANG.ngstroms are attached to an anchor surface to form a dendritic network which extends from 10 microns to 300 microns outward from the anchor surface. Catalyst particles which are also in the free molecule in the size range of 10 to 80 .ANG.ngstroms are attached to and dispersed throughout the support particle network. A process for making the reactor bed using binary gas phase nucleation of support particle and catalyst particle precursors is also disclosed.
