ESI-MS Analysis of Effluents from Medical Silicon Rubber 医療用シリコンゴムからの溶出物のエレクトロスプレー質量分析 荒川, 隆一 26968 Arakawa, Ryuichi 00127177 福尾, 剛志 26969 久保田, 直子 26970 田村, 正博 26971 Medical plastics Silicon rubber Catheters Effluents Electrospray ionization mass spectrometry (ESI-MS) Poly(dimethyl siloxane) Poly(ethylene glycol) Poly(propylene glycol) The catheter tubes of medical silicon rubber were dipped in ethanol. The effluents were fractionated by thin-layer chromatography (TLC), and their fractions were analyzed by ion trap electrospray ionization mass spectrometry (ESI-MS). The ESI mass spectra resulting from the main TLC fraction, R1=0.5 showed that the effluents were determined to be poly(dimethyl siloxane) (8 to 20 mer) that is a main part of a silicon rubber. The spectra for the origin in TLC showed that poly(ethylene glycol) (4 to 10 mer and 14 to 18 mer) and poly- (propylene glycol) (19 to 36 mer) as an antistatic agent were identified. journal article Mass Spectrometry Society of Japan 2000 VoR application/pdf Journal of the Mass Spectrometry Society of Japan 5 48 353 356 AA1254271X 13408097 https://kansai-u.repo.nii.ac.jp/record/11528/files/KU-1100-20000000-11.pdf http://hdl.handle.net/10112/5955 https://kansai-u.repo.nii.ac.jp/records/11528 jpn
