Malvern zetasizer zs90 dls spectrometer3/17/2024 ![]() ![]() DLS can also be used to probe the behavior of complex fluids, such as concentrated polymer solutions. It has been shown that the intensity of the ACF is the Fourier transformation of the power spectrum, and DLS measurements can therefore be equally well performed in the spectral domain. In time domain analysis, the autocorrelation function (ACF) usually decays, starting from zero delay time, and faster dynamics due to smaller particles leads to faster decorrelation of the scattered intensity trace. In the scope of DLS, temporal fluctuations are usually analyzed by means of the intensity or photon auto-correlation function (also known as photon correlation spectroscopy or quasi-elastic light scattering). Dynamic Light Scattering Dynamic Light Scattering instruments at Graz University of TechnologyÄynamic light scattering (DLS) is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or polymers in solution. ![]()
