with Ailent 1260 Infinity II quaternary system - openlab CDS 2.3 software, I would like to analyze polymers such as "polysiloxan" and also obtain Mw and Mn (number average molecular weight) using polystyrene standards and building a calibration curve. How can I build a calibration curve?
How do you advise me to proceed? is Better internal or external standard?
Please I need advice, I am a new user also with this technique.
Thanks a lot in advance.
