be conventional!
WHY?»
• • H I • newly developed HX-60 ™ ™ • • • • (60 MHz) NMR system opens many channels of research which have not been possible or practical with conventional old-concept commercial spectrometers. Over the past decade while Proton High Resolution NMR has become the most widely accepted technique for organic structural determina tions, researchers have strived to expand this highly sophisticated technique into other areas of research such as the Biomedical and Biochemical fields. With conventional instrumentation, this expansion became not only costly but also very impractical due to the time absorbed in performing instrument modi fications and exchanges. In practice, Multi-nuclei research had become — to many people — theoretical instead of practical. BRUKER, seeing the frustrations of the researcher, combined many years of electronic and scientific know-how with a logical outlook and has come up with "THE SYSTEM" for Multi-nuclei research. Now BRUKER is proud to introduce the HX-60.

Completely solid state modular design. Push button operation. Proton stabilization for all nuclei by means of frequency synthesized techniques. UNIVERSAL PROBE — for examination of up to eight nuclei without probe change. 5, 10, 13 and 15 mm spinning sample tube inserts. Variable temperature utilizing digital readout controller for temperatures from - 1 5 0 ° C to +200°C. Dual frequency modulation — 3-4 kHz (high resolution). Wide-Line — 40 Hz modulation. Calibrated wide sweeps utilizing internal proton stabilization: 1 H — 250 ppm proton stabilized 31 ρ — 500 ppm proton stabilized 13 c — 1000 ppm proton stabilized Homo- and Hetero-nuclear spin decoupling (selective and modulative). Independently swept f and I, channels allowing INDOR experiments to be performed. Pulsed Gates — increased leakage suppression for critical applications. For more detailed
