Avance-III-HD ss500

ss500
The 500 Magnex magnet

The ss500 instrument was recently upgraded (Feb’2016) to a Bruker Avance-III-HD system using the existing Magnex magnet. IMG_4384

 

 

 

 

 

It is equipped with a quadruple tuned  4-mm CPMAS probe, capable of carrying out various solid state NMR experiments such as MAS, CPMAS, HETCOR, REDOR, Quadrupolar Echo, etc. It can operate in double- or triple-resonance modes.

In Double Resonance mode:  1H / X = 15N- 31P;  In Triple resonance mode: 1H,19F /X=13C / Y= 15N-2H (50.7 – 76.7 MHz);   1H,19F/ X= 31P / Y= 29Si-65Cu (99.3 – 142.1 MHz).

VT range: -70 oC to +80 oC, 15 kHz max spinning frequency.

VT range: -20 oC to +80 oC;
Gradients up to 55 G/cm.

..and the A2B kit, which allows the use of existing Chemagnetics probes, such as the H/X 3.2-mm.

All probes are capable of measuring diverse nuclei, which makes this instrument ideal for materials and biochemistry research applications.

Users are encouraged to contact the NMR Facility staff.

The upgrade of the 500-MHz system to a Bruker Avance-III-HD-500 was attained with  support of the Head of the Chemistry Department Prof. Barbara Garrison and of the Associate Dean Andrew G. Stephenson. Contributions from the Office of the Vice President for Research at Penn State, Eberly College of Science, and Colleges of Agriculture, Engineering, and Earth and Mineral Sciences were also decisive on the purchase.

The NMR facility modernized its solid-state NMR capabilities, which enabled PSU to sustain its strong leadership in materials science and chemistry.
