Splet11. dec. 2004 · Using the silver-deposition/TOF-SIMS method, silver-cationized quasi-molecular ions were clearly detected from PDMS on solid surfaces, and their structure and molecular weight were evaluated. In addition, their images were observed without the interference of deposited silver. By applying to the analysis of paint defects etc., it was … SpletThe sputtering effects induced by energetic (MeV/u) multicharged heavy ions (e.g., 105 Rh and 140 Ba) were analyzed by the PDMS-TOF-SIMS technique (plasma desorption mass spectrometry-time-of-flight secondary ion mass spectrometry). Positive and negative secondary ionic species are identified: Na + , K + , Al + , Ca + , SiO2-.
