Analysis of Irganox 1010 in Cup of Instant Noodles (Styrene Foam) (GPC/MS)

Irganox 1010 in styrene foam cup for instant noodles was analyzed with GPC/MS using 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. KF-402HQ can provide the high sensitivity analysis without pretreatment of samples.
Refer to Simultaneous Analysis of Various Additives of Polymer in Polystyrene (GPC/MS).
