High Resolution FT-NMR â Online / in Process
First Generation NMR â 1998
Elbit-ATI/Foxboro NMR Second Generation NMR â 2003
Qualion
4. Lab version On-Line version
New magnet design â 30mm bore size
âą The amount of magnetic pieces that assemble the magnet reduced from 34 to 10. Reduction in
Mechanical Complexity
âą Bore size of the magnet was increased to 30 mm - improved temperature susceptibility
âą Improved temperature and shim stability.
New Digital Spectrometer Design - reduces footprint, improves signal processing capabilities
Probe - Improved Probe Q for Higher Sensitivity.
Software â Windows 7 â Improved Chemometric Capabilities
Third Generation NMR â Aspect AI NMR System
5. New magnet design solves the problem of:
Long term and short term Stability
Temperature sensitivity
State of the Art electronics:
Smaller foot-print
40 Shim coils on 2 single PCB
Integrated PCB for Shim & Heater Control
Digital RF & Acquisition â
improve SNR
New concept of Process Probe:
Entire sample pipe through
without contact with the system
Much better temperature
insulation
Higher Q (better sensitivity)
New Software:
Includes new algorithm for
standard and global Models
Fully automated process capacity
Extensive remote diagnostic capabilities
New Magnet System
