WebAn attenuated total reflectance infrared spectroelectrochemical (ATR-IR-SEC) technique has been developed that uses a surface-proximal doped Si ATR crystal as both the ATR optical element and the working electrode. This allows redox processes of monolayers of molecules attached to the Si surface to be probed through changes in their molecular vibrations as … WebGuha, S., & Dwivedi, C. B. (1986).

Electron ionization (EI, formerly known as electron impact ionization and electron bombardment ionization ) is an ionization method in which energetic electrons interact with solid or gas phase atoms or molecules to produce ions. EI was one of the first ionization techniques developed for mass … Meer weergeven Electron ionization was first described in 1918 by Canadian-American Physicist Arthur J. Dempster in the article of "A new method of positive ray analysis." It was the first modern mass spectrometer and used positive rays … Meer weergeven A schematic diagram of instrumentation which can be used for electron ionization is shown to the right. The ion source block is made out of metal. As the electron source, the cathode, which can be a thin filament of tungsten or rhenium wire, is inserted … Meer weergeven • Edmond de Hoffman; Vincent Stroobant (2001).
