## FAQ

- [1. What should I check if my MAS probe won’t spin up or seems to stall at low speeds?  A video demonstrating MAS probe spinning is available via the link provided.](https://dotynmr.com/faq/1-what-do-i-check-if-my-mas-probe-will-not-spin-up-to-specification/) - We’ll address the low-speed stalling issue first. Sometimes a rotor may appear to “stick” at a low spinning speed. This is often caused by a resonance in the rotor, which can result from uneven sample distribution or another imbalance. Follow the video link provided to see how to overcome this resonance and continue bringing the
- [3. Whom should I call to Clarify Specifications on an order I have placed?](https://dotynmr.com/faq/general-whom-should-i-call-to-clarify-specifications-on-an-order-i-have-placed/) - If you have questions about specifications, call Laura Holte, our sales manager at (803)738-6832), or you can call us at (803) 788-6497. It is best to ask for Dave McCree.
- [4. My MRI RF coil does not have the homogeneity I expect. What should I do?](https://dotynmr.com/faq/4-my-mri-rf-coil-does-not-have-the-homogeneity-i-expect-what-should-i-do/) - Homogeneity is sometimes hard to evaluate on the bench and we need to have a quantitative indication to use. Look at the discussion on Coil Lengths for guidelines on what typical field profile to expect in small coils. We recommend a spin-echo mapping method (see S. Crozier, K. Luescher, L.K. Forbes, and D.M. Doddrell, "Optimized
- [7. What is your shipping address?](https://dotynmr.com/faq/7-what-is-your-shipping-address/) - Our shipping address is: Doty Scientific, Inc, 700 Clemson Rd. Columbia, SC 29229 USA
- [5. How can I spin a liquid or semi-liquid in a rotor without leaks?](https://dotynmr.com/faq/5-how-can-i-spin-a-liquid-or-semi-liquid-in-a-rotor-without-leaks/) - First some liquids can be very challenging to spin without leaks and there will be a limit for most methods to the speed that can be achieved before leaks occur. The Doty MAS sealing cells for XC and DI type spinners are the best starting point for these types of samples. We have a variety
- [6. What turbine caps do I use for extended VT?](https://dotynmr.com/faq/6-what-turbine-caps-do-i-use-for-extended-vt/) - Most of our turbine caps are not rated for the full VT range of the probe. GFT caps have the widest VT range. For use at XVT the GFT caps may have to be glued in. Glue the caps into the rotor with a good high temperature epoxy. The caps will then have to be
- [6. Is there anything special I should do for return of an item from outside the United States?](https://dotynmr.com/faq/6-is-there-anything-special-i-should-do-for-return-of-an-item-from-outside-the-united-states/) - It is important to check with your country’s customs office or your customs broker. Sometimes there are special forms that you need to fill out before returning an item. (It may be helpful to have one of our international sales or service representatives help you with the customs, if the probe has to come back
- [2. Whom can I talk to with questions about probe or coil operation or about problems I am having?](https://dotynmr.com/faq/general-whom-can-i-talk-to-with-questions-about-probe-or-coil-operation-or-about-problems-i-am-having/) - You can call us at (803) 788-6497 and talk to Dave McCree, or sometimes Laura Holte our sales manager at(803) 738-6832 can assist you. If you prefer email, service@dotynmr.com. If you need to send a fax, (803) 736-5495.
- [1. Do you have international sales or service offices?](https://dotynmr.com/faq/general-do-you-have-international-sales-or-service-offices/) - Yes. We have had a European Sales and Service office for many years. Presently, the authorized service center is in Germany. ROTOTEC SPINTEC will be able to help with service of Doty products in Europe. We have additional sales representatives, RS2D in France and Belgium, LA Systems in Japan, and BK Instruments Inc., in South
- [4. What should I do if I want to send my probe or coil back for service?](https://dotynmr.com/faq/what-should-i-do-if-i-want-to-send-my-probe-or-coil-back-for-service/) - First, contact us about the problem. Call or email us with a description of the problem. It is important to provide the name of your institute, and the Doty probe or coil serial number. (The serial number starts with “DSI-“ and is usually located on our probes where shown below.) The serial number can be
- [3. What is the best procedure to use to spin an MAS rotor to avoid problems?](https://dotynmr.com/faq/3-what-is-the-best-procedure-to-use-to-spin-an-mas-rotor-to-avoid-problems/) - There are normally instructions in the user manual for the correct method for your probe. However, some general instructions are: • Start with about 10 psi of bearing gas pressure. • Add a couple of psi of drive pressure to get the rotor spinning. • Gradually increase bearing and drive together keeping bearing 10 to
- [2. I have spikes in my FID.   What is causing this?](https://dotynmr.com/faq/2-i-have-spikes-in-my-fid-what-is-causing-this/) - "Spikes" in the FID are asynchronous noise bursts at the observe frequency being generated somewhere in the NMR system. There are several possible sources for this noise including arcing in the probe or sample coil. A bad cable or poor quality cable that has recently been put into the system could cause the problem. Devices
- [8. Do I need a Return Authorization Number?](https://dotynmr.com/faq/8-do-i-need-a-return-authorization-number/) - Yes, we do require prior authorization. Please contact us for a RMA number before shipping the probe and tuning elements to us for repair. Also, be sure to include full contact information, Doty probe (or coil) serial number information and a complete description of problems on paper in the box with the product to avoid
- [5. What information should I send with the probe?](https://dotynmr.com/faq/general-what-information-should-i-send-with-the-probe/) - Enclose a letter with the probe detailing the problem, the associated RMA number, and contact information including a contact person and phone, email, address. Please also send all tuning elements of the probe back so that tuning for all nuclei can be checked during repair. It saves time later if you also enclose the address for return of
