NMR Probe for Static Oriented Samples |
|---|
| The following properties are those which are unique to Solid-State NMR Probes dispersed to investigate static oriented biological samples.
- Static Solid-State NMR Probe |
|
Solid-State NMR Probe |
| Four components are used as tuning elements in the NMR probe. |
 |
A) chip capacitor B) inductor C) variable capacitor D) transmission line |
Sample Geometry |
In general, two different sample geometry are used. A round NMR tube is used Left probe: 5mm Right probe: 12x12x2.6 mm |
 |
| Circuit Diagram |
| Shown below is a typical double resonance probe circuit. The picture on the left expresses the probe circuit in a diagram while the picture on the right depicts the probe circuit as it is implemented in the NMR probe. |

Grounding |
The distances between RF components and the probe cap are too close to be ignored. To provide reliable ground, we use Beryllium copper fingers to ensure good electrical contacts between the ground planes of the different layers to the cap. We also gold-plated the ground planes, the Beryllium copper fingers, and the cap to prevent copper corrosion. This is very important for overall probe reliability. |
