Poly(Ethylene Terephthalate) (1) (HFIP-806M)

Poly(ethylene terephthalate) was analyzed using GPC HFIP-806M (a column for organic SEC (GPC)). PET resin is commonly used as a raw material for beverage bottles. PET usually contains small amounts of oligomers as impurities. For the analysis of PET, CF₃COONa should be added to HFIP eluent.
