measuring fluid viscosity

#1 Post by matsmcfly1 » 2021.06.11 07:33

I have never used SAXS in my work before, but I am considering it for a potential experiment. In my very limited knowledge I thought that we might be able to use SAXS to measure the viscosity of a fluid that contained nanoparticles - is there a way that this can be done? If particles of known shape and monodisperse size were used, I assume we can fit the data to obtain the radius of gyration, but from this is it possible to calculate the diffusion coefficient or fluid viscosity?

I dont think, you can get viscosity from SAXS. But Anton Paar have an instrument, which can measure both SAXS and viscosity at the same time:
