Portable Low-Resolution NMR Analyzer - Spin Track

Analyzer is designed to perform:
  • All standard NMR applications
  • Development of new NMR-based techniques
  • Teaching quantum physics, NMR, analytical chemistry in Universities and Colleges
NMR analyzer Spin Track comprises functional parts (probes, preamplifier and duplexer, TX Power Amplifier, Sequence Generator and PC Interface, Data Acquisition System, NMR Transceiver) which can be purchased separately and used for the specific needs of an advanced customer (see example of connection assembly). Depending on the required magnet system the Spin Track can be used as NMR relaxometer or high resolution NMR spectrometer.

  • Frequency range of the NMR spectrometer module: 5..60 MHz
  • Ringing time for 10 mm NMR probe is 8 ms
  • Probe tube diameter: up to 10 mm
  • Changeable preamplifiers and 50 Ohm matched duplexers with self bandwidth of 5 MHz
  • Customer-defined set of sensors (5, 10 and 40 mm test-tube magnet systems, NMR surface sensors)
  • Adjustable TX output power up to 500 Watts
  • Adjustable RX channel gain up to 107
  • RX Sensitivity better than 1 mV (conditions: signal to noise ratio 3)
  • Adjustable digital filter bandwidth from 100 Hz up to 1 MHz
  • Pulse sequence length up to 64K events with resolution 100 ns
  • Quadrature 64Kx10-bit data acquisition system
  • Complete control of functions via personal computer - USB 2.0 Connectivity
  • Fast sensors replacement
  • Compatible with all Microsoft® Windows® operating systems
  • Relax Software

Software

The product software, Relax, is a powerful tool containing many standard NMR relaxation routines and applications, and can also be used to create new pulse-sequences, pulsed field gradients, gains and attenuations, post-processing methodolgies of considerable complexity. The built-in script language is based on a widespread Pascal syntax and is enriched with commands for fitting, Fourier and Laplace transforms, Low-pass filtering, etc. The script supports dialogue windows, static messages, user-defined diagrams, data manipulation procedures. Relax also allows direct processing of data obtained when utilizing Spin Track as a high-resolution NMR spectrometer.
