  The analysis of volatile components in anti-inflammatory tapes by means of Cryo-TOF-SIMS

  P02089_The_analysis_of_volatile_components_in_anti-inflammatory_tapes_by_means_of_Cryo-TOF-SIMS.pdf

  Surface analysis methods generally need ultra high vacuum (UHV) condition. Therefore, it is impossible to analyze the samples including much volatile components which prevent exhaust of vacuum chamber (i.e. loadlock chamber).
