acrylic acid polymer with GPC
Posted: Fri Oct 17, 2008 1:10 pm
I have the following question. When analysing this polymer a common pH of the mobile phase is between 7 and 9 when using a polymeric column. As I understand the polymer is than negatively charged.
But what kind of interaction would occur if the pH was low? What is the role of the added NaCl?
