How can i measure the molecular weight or the length of the polymer chains directly without and rheological test?

I can measure the length chains from the rheological test through testing of viscosity ,but this give me approximate result, therefore i look for any exact way for that test.

What is the relation between the surface tension and stability of nanofluids.?some

sometimes the surface tension of nanofluid increases and sometimes decreases with the nanoparticles concentration increasing.There is no constant behavior for that.Is there any useful test about that.
