Analysis of Antioxidant in Polystyrene (GPC/MS) (KF-402HQ)

Antioxidant (IRGANOX ® 1010) in Polystyrene was analyzed with GPC/MS using GPC KF-402HQ (a semi-micro organic SEC (GPC) column). Only a low molecule weight domain can be poured into a mass spectrometer (MS) by using GPC mode. Therefore, it is not necessary to pretreat.
