Ultrahigh Vacuum Scanning
Probe Microscope JSPM-4610






SPM_Device




Since its invention in 1982 Scanning Probe Microscope (SPM) confidently holds an important position in surface science. Nowadays it is an essential instrument for surface investigation. Along with this the need for clean sample surface by observation using SPM has grown up and high vacuum environment is necessary to ensure clean sample surface for imaging.

High Vacuum Scanning Probe Microscope (HVSPM) designed by JEOL Corporation is the instrument showing maximal opportunities for surface analysis. When creating this scientific instrument JEOL Corporation has used its many years' experience in manufacturing of scientific instruments .

Nuclear Magnetic Resonance spectrometer Bruker AVANCE 400
 
 
  NMR  

Multi-functional nuclear magnetic resonance spectrometer is designed for structural and dynamic researches at the nanoscale in solids, including both inorganic and organic materials, as well as for study of liquid-phase systems, for study of molecules and molecular systems structure and properties, dynamics of intra-intermolecular exchange processes, reactivity of new classes of organic, organometallic compounds and polymers in solution.

Spectroscopy:

  • nuclear magnetic resonance (nuclei of majority chemical elements isotopes, temperature range 77-2000 K, the pulse frequency range up to 20 MHz)
  • NMR relaxation
  • nuclear quadrupole resonance (nuclei with J> 1)
 
 

 

The base of SPM&RS Center is composed of: ultrahigh-vacuum scanning probe microscope, NMR and EPR spectrometers, optical microscope, magnetron sputtering unit, high-precision analytical balance, derivatograph, single-beam UV-spectrophotometer, freeze-dryer. This equipment was developed and produced by the pre-eminent manufacturers of vacuum and analytical equipment and is certified, that is the necessary requirement when buying analytical equipment.
