High Resolution FT-NMR – Online / in Process

First Generation NMR – 1998 Elbit-ATI/Foxboro NMR Second Generation NMR – 2003

Qualion

Lab version

On-Line version

New magnet design – 30mm bore size

• The amount of magnetic pieces that assemble the magnet reduced from 34 to 10. Reduction in

Mechanical Complexity

• Bore size of the magnet was increased to 30 mm - improved temperature susceptibility

• Improved temperature and shim stability.

New Digital Spectrometer Design - reduces footprint, improves signal processing capabilities

Probe - Improved Probe Q for Higher Sensitivity.

Software – Windows 7 – Improved Chemometric Capabilities

Third Generation NMR – Aspect AI NMR System

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 –

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


NMR Sample System and Placement



NMR Lock - External 7Li Lock @ 22.5 MHz Shim DACs Built into the Magnet Enclosure

Matrix Shimming Performed

by Optimizing FID RMS
