we have light scattering instrument of Malvern Nano ZS series. I need to do a studies on change in Molecular weight of the sample. But im unable to perform it. I have seen a drop down menu in the setup but i need some expert help.
I have electrospun pure ABS solution and measured the diameter and it was measured as 500s nm averagely. But surprisingly the fiber diameter decreases to 100s nm averagely while loading of MWCNT....
