Agitated reactor with in situ nanoparticle size control by light scattering photon correlation spectroscopy

We propose a simple design of the precipitation reactor vessels permitting measurements of the mean size of nanoparticles by light-scattering photon correlation spectroscopy. The measurements are conducted in connecting transparent capillary array in conditions free of turbulence, which otherwise perturb such measurements. A satisfactory quality of the autocorrelation function has been obtained in test measurements of 100 nm latex nanoparticles.
