Hello,
I would like to ask if anyone here know conditions for analyzing HDPLE (high-density polyethylene) and LDPE ( low-density polyethylene) with SEC/GPC method? Problem is solubility this two samples. So anyone know how to prepare this samples, which type of column should I use, mobile phase, standard...?
Thank you in advance for all answers.
bye
