Your wishlist for 2014?
In the last two months, we were privileged to participate in the Southeastern NMR conference in Tallahassee, Florida in the US, and the Asian Pacific NMR & ANZMAG conference in Brisbane Australia. Discussions about DNP were ...
BMAX Probe 100 Times Faster
Could a BMAX Probe be 100 Times Faster than your current solids probe? Possibly. How could that be true? The following is one of the most useful expressions for predicting S/N following a single π/2 pulse at thermal equilibrium: The parameters VS/τ90P1/2 are determined by the NMR probe, and for 13C in Doty's 3 mm D1-3 at 11.7 T, it is ~1 (common units). ...
Doty Scientific awarded SBIR Research Grant from NIH for development of a 30 K MAS-DNP probe
Doty Scientific was awarded a Small Business Innovation Research (SBIR) research grant from the National Institutes of Health (NIH) for development of a 30 K MAS-DNP probe. The award started on September 30, 2013. This SBIR project will enable 30 K MAS-DNP operation by developing: (A) the needed high-stability 30 K helium spinner technology, (B) the needed high- efficiency closed-loop cryogenic helium recycling system, and (C) the complete quad-resonance (1H-13C-15N-electrons) DNP probe with auto sample exchange and extended variable temperature (XVT) operation for ...
Important Facts When Purchasing a Solids Probe
Important Facts When Purchasing a Solids Probe Do you expect to be doing long acquisitions with high-power decoupling at over 400 MHz on lossy samples? If so, then you want a probe in which the 1H field is not generated by a solenoid. The DE coils on Doty BMAX probes work well for these applications. Is proton efficiency or X/Y performance the most important for your experiments? Doty's new BMAX probe is optimized for X/Y ...
