Liquids NMR Probe
Many in the field of NMR immediately relate Doty Scientific with Solids NMR.  We are proud of our contributions to NMR Solids, however, we would like people to know more about our contributions to liquids NMR as well.

Doty Scientific, an established leader in large-sample high-resolution (liquids) coil technology and solids NMR, is using the latest in laser cutting, compensated laminates, and thermal gradient minimization with alumina coilforms to bring its Super-B1 coils to the field of high-resolution liquids NMR.

Following are examples of custom liquids high-resolution probes designed and built by Doty Scientific :

Recent results at the Advanced Imaging Research Center, Southwestern Medical Center at Dallas, Texas, USA, demonstrate the quality and versatility of Doty liquids probes.

13C spectrum for a perfused heart in DOTY 25 mm 1H/X liquids probe at 9.4 T. The heart was perfused with hyperpolarized 2 mM [1-13C]pyruvate and natural abundance, unpolarized 2 mM octanoate. The metabolic products lactate and alanine are visible after a single 66 degree detection pulse. The octanoate effectively blocks production of the bicarbonate, which would normally be about the size of the lactate. The linewidths were ~12 Hz for 13C on the beating heart.

Our discussion of liquids NMR, would not be complete without mention of our BMAX probes and the XC MAS probes. These versatile probes were designed specially to provide adequate resolution for the user to do HR MAS on solids, tissues, or liquids.
