DRX-499

DRX-499 has remained, for many years, the mainstay 500 MHz spectrometer for most of the research work using NMR in the department. It continues to be a popular spectrometer that is very reliable and stable. It is used for multinuclear 1D as well as 2D spectra acquisition.

Default 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.

Backup probes that are installed occassionally :

Bruker triple resonance HCP : 1H { 13C, 31P } with XYZ-gradients

Bruker triple resonance HCN : 1H{ 13C, 15N} with XYZ-gradients
