报告简介：
This seminar will introduce several mass spectrometry based analytical methods and their applications in analysis and surface chemistry. Also, preparative deposition of ions as a method for surface modification will be discussed. Mass spectrometry provide a wealth of tools for generating and manipulating gas phase ions. Ambient ionization and deposition of noble metals ions will be presented. Surfaces plasmon properties are prepared by deposition of noble metal ions. This talk will also briefly showcase several recent developments such as low volume (pL) sample ionization, zeptomole sensitivity, nanocoulomb charge delivery, and in source preconcentration.
