Low Energy Ion Scattering Mass Spectrometer (LES)
Quadrupole mass spectrometer with EI (Electron Impact) ionizer source .(Extrel –USA)
Low Energy Ion Scattering Mass Spectrometer (LES) is a custom built instrument in our laboratory to probe chemical reactions that occur on the surface of ice. The unique property of this machine lies in studying top few mono layers of Molecular materials with near thermal energy ion scattering.
It is one among few instruments that is available all over the world and we are among few groups in the world who work in ice chemistry through LES technique.
