Abstract: | |||||
Several methods are discussed and applied for minimizing distortions m
dynamic light scattering (DLS). Multiple scattering, a very common
phenomenon in DLS experiments, is discussed. Distortions caused by multiple
scattering and its influence on correlation data are analyzed in detail. Five
different methods are applied in simulations of suppression of multiple
scattering in DLS experiments. The effect of foreign large particles, such as
larger particles left by previous experiments, fast sinking dust in the sample
suspension or agglomerations of the sample particles, are discussed and
analyzed. Two 'dust' removal methods are discussed and applied on anticontamination
simulations and real experimental data. Investigations are
carried out considering samples flowing with velocities and also distortions
coming from stray light. An area difference method is introduced in detecting a
sample's velocity and stray light. From the results of simulations and real
experiment data, the conclusion can be made that the methods discussed in this
thesis perform well in minimizing the distortions in DLS experiment.
