Rat Spinal Cord Imaging on Unique Imaging Coils
A customer contacted us with a request to build custom coils for their studies on rat spinal cord, both in vivo and ex vivo, motivated by performance issues related to RF homogeneity and shielding exhibited in current OEM coils. A quadrature volume coil with 56 mm ID was constructed for the in vivo imaging (on awake or mildly anesthetized rats), and was utilized at the study onset. The volume coil’s excellent sensitivity made it possible to generate high resolution ...
A Large Volume 20 mm Liquids NMR Probe
Doty Scientific recently delivered a narrow bore liquids NMR probe with a 20 mm sample volume for use in a 400 MHz narrow bore system. Unique Liquids Probes Narrow Bore or Wide Bore. 5 mm to 20 mm sample options Extended Temperature (XVT) to +300 oC - with sample size 5 mm Many tuning options: H/X/lock, H-F/X/lock, H/C/N/lock, H/F/X/lock.
We hope to See You at ENC or ISMRM
ENC (April 24-29) and ISMRM (May 7-12) are fast approaching. We are excited to attend these conferences in person. It seems so long since we met face to face. For those coming to the ENC in Orlando, Florida, USA, come by Suite Magnolia C, Sunday through Wednesday evening from 7:00 to 11:00 PM. (And yes, there will be ice cream, including one non-dairy sorbet.) For those attending ISMRM in London, come by and see us in Booth D32. If you missed ...
Some Brief Comments on the Source of Artifact Suppression in NMR Spectroscopy
By Paul D. Ellis, Ph.D. The intent of this discussion is to bring clarity to some outstanding efforts to remove unwanted signals from an NMR spectrum. There appears to be some confusion relative to the origin of artifact suppression methods by which artifacts can be removed from an NMR spectrum be it from liquid or solid samples. This confusion may be mostly amongst young investigators, who are younger than the original research. To place this comment on an age scale, the original ...
Doty Scientific is looking to fill the following positions:
Doty Scientific is looking to fill the following positions: NMR Scientist/ Engineer. The successful candidate is expected to have a PhD in chemistry, physics, electrical engineering, or related, and experience with modern high-field NMR methods and associated equipment. Studies or experience in Dynamic Nuclear Polarization (DNP) is highly desirable. Responsibilities will include setting up and running NMR experiments using state-of-the-art NMR probes and communicating their effectiveness. The work will include testing of products, demonstration of new capabilities, customer service, product development, and ...
Waveguide Paper Published
We at Doty have been investigating various ways by which a probe designer can deliver millimeter waves (mmw) efficiently to the sample in a magic angle spinning probe once the mmw have arrived at the probe. A paper summarizing these efforts has recently appeared in the JMRO, i.e. F. David Doty, Glenn N. Doty, John P. Staab, Yuriy Sizyuk, and Paul D.Ellis, “New Insights from Broadband Simulations into Small Over-moded Smooth and Corrugated Terahertz ...

A Practical Guide to Setting Up Diffusion Measurements
By Paul Ellis As an elder statesman in the area of solid state NMR spectroscopy, it has become obvious that pulsed field gradients (PFG) experiments are and will continue to be important in the future. Our liquid state colleagues have enjoyed the benefits of PFG for many years. For example, PFG can remove artifacts within the transverse plane and hence reduce the number scans needed to complete a phase cycle. Likewise, PFG can be utilized to select coherences in experiments, again ...
