The probe compartment of rf coil with tubing for sample delivery; US quarter is shown for scale.
One half of the five turns Helmholtz spiral rf coil with tubing channel seen below the coil.
The tubing of flow package goes into the channel between the halves of the coil across the region of the highest coil sensitivity.
A single scan spectrum of water. The linewidth is 0.59 Hz (0.02 ppm).
A 16 scans spectrum of methanol.
A 16 scans spectrum of 1-propanol.
An axial image of the sample delivery tubing filled with water. The tubing ID was 1.02 mm.
An image of the laminar flow of water in the sample delivery tubing. The flow rate was 0.001 mL/s.
