AV-500

AV500AV500 provides the latest NMR capabilities at 500 MHz to tackle a wide variety of research problems. The instrument can generate a maximum Z-axis magnetic field gradient of 56 Gauss/cm to perform most of the experiments that rely on coherence selection using gradients and selective peak suppression using gradients. Shaped gradients can be generated with the aid of Bruker Shape Tool.

Currently installed Probehead

 

Bruker multinuclear inverse BBI - 1H {X} with Z-gradient

X nuclei range from 107Ag to 31P. This probe is optimized for best sensitivity in 1H. Well suited for indirect detect experiments.

 Other Probeheads available :

 Bruker triple resonance TXI  - 1H{13C,15N} with Z-gradient

 Bruker double resonance S-EX : 13C {1H} 10mm with Z-gradients - ultra high temperature probe - max 200 C operation

Note: this probe requires dedicated 10 mm NMR sample tube and increased volume of sample compared to conventional 5 mm preparations.
