400 MHz NMR Console with Robotic Sample Changer

The University of Ottawa is pleased to invite qualified proponents to submit a proposal for a 400 MHz NMR Console with Robotic Sample Changer System.  

The required infrastructure must consist of a state-of-the-art 400 MHz three-channel NMR console, and several associated essential accessories. The console should incorporate a dedicated system control unit with its own CPU for control of all radiofrequency channels, gradients, pulses, and triggers. Also required is a standard bore shim system to interface with our existing UltraShield 400 MHz standard-bore magnet. This must include an ultrastable shim current board and the bore magnet system sample transfer system for sample insertion and ejection. A fast single channel gradient amplifier, essential for rapid pulsed field gradient shimming and gradient-enhanced spectroscopy are required. A system to facilitate the regulation of sample temperatures must be integrated, providing a temperature stability of at least 10mK/K and a digital temperature sensor resolution at least 0.1°C. Requisite radiofrequency amplifiers for 1H/19F and X channels, a deuterium lock, and necessary preamplifiers must be included. The system must come with a new NMR Workstation running Windows and appropriate NMR software. A triple resonance 5 mm broadband probe optimized for X-nuclei observation with 1H and/or 19F decoupling and for 1H observation is requested. The probe should be optimized to have a minimal 19F background signal. The probe should be capable of performing variable temperature experiments in the range from at least -50 to +100° C. In order to maximize accessibility and throughput of the instrument, a 60+ position sample changer is essential to the research programs. The capabilities of this instrument must enable accurate and rapid characterization of small organic molecules containing NMR active nuclei including, but not limited to, 1H, 13C, 31P, 15N, and 19F.

Specifications listed in Appendix A – Technical Specifications Compliance Form of this RFP are the mandatory minimum requirements for the 400 MHz NMR Console with Robotic Sample Changer System.
