A higher field version with a fast-MAS 1.3 mm spinner is being developed.Fluorine Quad H/F/X/Y HR-Solids 4 Efficient, high power RF channels Dedicated 19 F and 1H channels for 1H and 19F operation simultaneously 2 Broadband channels, X/Y Enables 1H and 19F high-power decoupling (and 2H decoupling on the X Channel) Fast-MAS 3 mm Extended VT range: NB -150 to +150 °C
New paper: Guide to Simulating Complex NMR Probe Circuits
A new published paper in Concepts in Magnetic Resonance. Significant efforts have been put into probe circuit designs since the inception of Doty Scientific. Though celebrated for the spinning advancement, the first circuit on the original MAS probe was also far more efficient and had improved signal to noise -- enabling much shorter acquisition times. Early probes were all fixed tuned. Doty introduced the first multinuclear MAS probe. In the years since, we have gone from H/X at 100 MHz to quad ...

A Practical Guide to Diffusion Measurements – Expanded
Earlier this year, we introduced a white paper, A Practical Guide to Setting Up Diffusion Measurements Utilizing Pulsed Field Gradients. We are re-introducing the paper with additional material to include solids diffusion methods. The paper is now presented in three parts. Part one is the original material - with part 2 and 3 being new material. A Practical Guide to Setting Up Diffusion Measurements Utilizing Pulsed Field Gradients. Daniel Arcos, John Staab, Bibhuti Das, Paul D Ellis, and F. David Doty Part ...
To Deuterate Your Proteins – or Not to Deuterate? That is the Question.
MAS has long been an integral technique in Solid State NMR, beginning with investigations on typically inorganic samples, but quickly moving to biological samples with ever increasing molecular weight. The resulting complexity of the NMR spectrum has lead to the use of High-resolution inverse 1H detection in Solid State NMR spectroscopy for large molecules. New developments in protein biochemistry and fast spinning have contributed to this rapidly evolving area of NMR. Bibhuti Das, Paul Ellis and F. David Doty present ...
Introducing: Doty WB Ultra-Range NMR MAS Probe
At the Rocky Mountain Conference in Snowbird Utah, USA we introduced a new wide bore MAS probe we call the “WB Ultra Range”. It features a broad temperature range, a broad tuning range, and a broad range of spinner options. The Doty WB Ultra-Range MAS Probe Broad Temperature Range -170 oC to +270 oC (and ultimately higher) Fully Multinuclear 31P to 103Rh Broad Tuning Range with Most Tuning Inserts Double-Tuned 1H/X or Triple-Tuned 1H/X/Y Broad Range of Spinner Options 7 mm, 5 mm, ...
