Fig. 5: SALS static and dynamic light scattering on diluted colloidal suspensions.
a Static scattered intensity vs q after optical background subtraction, for a diluted suspension of SiO2 colloids. Error bars are the standard deviation over a time series of scattering images. b Representative g2 − 1 functions measured with the SALS camera for a a diluted suspension of PS particles, with no optical background subtraction. c q dependence of the relaxation time of the correlation functions shown in (b), with additional data points obtained a larger angles, using the DLS45 and DLS90 COLIS measurement lines. Error-bars are calculated using the covariance matrix from the fits and are smaller than the symbols.
