“Kurgan” (LC-NMR/MS) Avance – 600IV

Kurgan is a Bruker Instruments Avance III 600 console, 14 T Ultrashield magnet NMR spectrometer fitted with an LC-MS system.

Console Capabilities

The console of Kurgan is equipped with 3 RF channels, 4 amplifiers, and the capability generate 3-axis gradients of arbitrary shape. Each RF channel is capable of generating hard and shaped pulses over any nucleus. The four amplifiers consist of two linear amps covering the x-nucleus frequencies up to phosphorus, one for hydrogen and one for deuterium.

The controlling computer is an HP desktop computer running CentOS 5.5 Linux. The Bruker software, TopSpin, should be capable of executing any desired multi-dimensional experiment, with the only limits being the type of nuclei observed.

Kurgan is also equipped with an automated sample changer that can accommodate boxes of 96 samples in 1.7 mm tubes, or up to 46 individual samples in spinners on the outer ring. It is still possible to load samples in manual mode, however, this procedure requires users to be first trained and approved by NMRFAM staff.

Available Probes

  • 1H{13C,15N} 1.7 mm cryogenic probe
  • 1H{13C,15N,31P} 5mm cryogenic probe (ASTM 31P S/N xxxx and 90% Formamide 15N S/N xx)


The base rate for time on this machine is $8.00/hour for publishable work or $250/hour for proprietary work.
