PARTICLE CLUSTER SIZING IN DOWNER UNITS. AN APPLICABLE ACROSS DOWNER SCALE METHODOLOGY

摘要

Data analysis from downer requires a comprehensive methodology for setting the data baseline. This can be accomplished using solid mass balances as proposed by A. Lanza et al (1). This analysis involves an iterative calculation. Each signal baseline is defined as, X+ n σ_x where X is the signal average; ov is the signal standard deviation; and "n" is a baseline parameter (2). By using this methodology the noise resulting from secondary reflection is eliminated and all valuable data is kept in the time series.
