Hi, guys:
Could anybody do me a favor? I am confused by the definition of
polydispersity index(PDI) of particles.
from light scattering, I got PDI value sth like 0.04, however, I know there
is another definition of PDI which is larger than 1, which is defined as:
PDI= Dw/Dn
so how can I get PDI like 0.0 sth ?
thanks | b***e 发帖数: 115 | 2 just as sb in my lab got the result of polydistribution of Mw/Mn <1
