Unformatted text preview: obal warming. High-pressure CO2 can plasticize glassy polymer membranes. Membrane plasticization has a negative impact on gas separation involving natural gas purification (CO2/CH4 separation), the removal of CO2 from power plant emissions (CO2/air separation), and hydrogen purification (CO2/H2 separation) for use in fuel cells and oil refining. As a matter of fact, properties of a membrane strongly depend upon the chemical structure and microstructure of the polymer. Therefore, the synthesis of novel polymers with well -defined structure as designed membrane materials, will not only contribute to the development of new membrane materials but will lead to a significant advancement in the science and technology of membranes as well. This keynote lecture presents polymeric separation membranes for greenhouse gas, especially CO2, recovery against global warming. 52 3rd ICYC 2010 Universiti Sains Malaysia KN-13 23rd-25th June 2010 DEVELOPMENT OF NEW CONCEPT EVOLVED GAS ANALYSIS WITH SOFT IONIZATION MASS SPECTROMETRY Takahisa Tsugoshi National Institute of Advanced Industrial Science and Technology (AIST), AIST Central 3, 1 -1-1 Umezono, Tsukuba 305-8563, Japan E-mail: On EGA technique as thermal analysis, interface device between a furnace and a mass spectrometer (MS) that is superior for EGA to other techniques in terms of high sensitivity, identification of unknown species and real-time monitoring of pyrolysis behavior, is very important device because the interface device might cause to trap and/or to denature analytes as pyrolyzed unstable species. The capillary interface that is the most popular device between TG and MS as an application of EGA -MS were generally kept at 200 °C, hence it has a problem mentioned above. As a solution of this prob lem, a skimmer interface has been developed and applied to new EGA instrument. On the other hand, a mass spectrometer with electron ionization that is one of the most popular ionization techniques offered complex spectrum included obstacle peaks due to the fragmentation during ionization. The ion attachment (IA) technique does not prod...
