Bruker AVANCE III 500 MHz (AV 500) multi nuclei solution NMR Spectrometer has been installed in the SAIF/IIT/M during Nov 2007. The following are the key features of the instrument

    11.7 Tesla super-conducting long hold magnet, actively shielded with standard bore (narrow bore: 5 - 5.4 cm), built in cryo-shims, 34 channel room temperature shims.

    Stable lock compatible with pulsed field gradients, gradient shimming with low heat dissipation. Automatic gradient shimming, Deuterium lock.The basic unit has four RF channels to carry out triple resonance experiments, phase resolution better than 0.1 deg, frequency resolution better than 0.1 Hz, Provisions for observing all nuclei including 19F ‚amplifier power: 300 W (LF) & 100 W (HF)‚high band and broad band pre-amplifier, shaped pulses generations all RF channels, dual 21-bit ADC.


  1. HP workstation with LCD TFT monitor and Windows XP based TOPSPIN -2 software with one additional software for processing.
  2. Auto sampler for 24 samples.
  3. Air compressor and drier.
