A scanning mobility particle sizer (SMPS, TSI Model 3934) and a white-light optical particle counter (OPC, as described by Umhauer 1983) are combined. With these two instruments, fast and non-intrusive on-line measurements of particle size distributi

Against the background of inaccurately measured wood particle dimensions, applying the three-dimensional (3-D) image analysis–based particle size characterization system Partimac 3D XL in pre- liminary tests, metal platelets with various aspect rat

Gas density affects the gas holdup in bubble columns. Even at atmospheric pressure, different gases produce varying gas holdups. This contribution explores the causes for variations in gas holdups occurring for different gases. Differences in the bub

The influence of particle aggregates on particle sizing with optical particle counters (OPC) is demonstrated. First, the scattered light intensity for a specific OPC is calculated for clusters of 2, 3 and 4 spheres in the size range of 0.01–2 μm.

An optical particle counter of the type first described by Umhauer (1983) was modified for the purpose of in situ measurements at high concentrations to achieve very low coincidence errors. Therefore, the optically defined measuring volume was reduce
