摘要: There are few techniques to measure in situ the size distribution and density of fluidized nanoparticle agglomerates. Visualization techniques, which most applied approach, currently have two important limitations: (1) they do not allow a continuous determination terminal velocity agglomerates, because it is necessary stop fluidization (2) often, agglomerates tracked very dilute zones bed, typically splash zone, where likely representatives for whole bed. In this communication, we propose sampling technique that allows determine larger than ∼20 μm continuously, situ, work with concentrations higher other reported techniques.
