DIUTHAME is a matrix-free ionization method using “through hole alumina membrane”. This characteristic structure can also be used as carrier and a filter in a pretreatment procedure. PEG was selectively removed from “PEO monostearate” (the mixture of PEO components with different end groups) after methanol solution go thorough DIUTHAME. Antioxidants in resins are successfully observed without filtering after extraction. DBDE in PS are detected clearly in negative ion mode.
