WebAt short time delays, the correlation is high because the particles do not have a chance to move to a great extent from the initial state that they were in. The two signals are thus essentially unchanged when compared after … WebThe CUMULANT analysis is based on a series expansion of the measured correlation function and provides an estimate of the average particle size, and to a lesser extent accurate particle size width.

WebFeb 1, 2024 · The analysis of different fractions present in solution (regularization fit) gave a much better fit of the data and confirmed the presence of larger species (fraction 2) in solution (Table 1). However, the proportion of this second fraction was very low (>0.1%) in … WebCUMULANT is however based on the assumption that only one particle population is present (monomodal), which must have a gaussian distribution around the average particle size. As in all the DLS experiments, the particle radius is computed from the … WebSep 15, 2014 · Check the actual definition of the Asymptotic st. error, and the other parameters of the fit, which in this case seem reasonable. Please check also the other details of the fitting: "degrees of freedom (FIT_NDF) : 97 rms of residuals (FIT_STDFIT) = sqrt(WSSR/ndf) : 0.0420015 variance of residuals (reduced chisquare) = WSSR/ndf : … show books i have read
