VARIABLE TEMPERATURE DATA
VT DATA FROM PHOENIXNMR PROBE AND MODULES UTILIZING 207PB NMR SIGNAL
These data were all acquired at 14.1 T, using a single PhoenixNMR HXY probe body and merely exchanging different probe heads, using the 207Pb NMR signal from lead nitrate. See Experimental Details, below.
The HXY Premium Probe is typically quoted with a VT range of -125°C to +125°C. The standard VT range for the HX Probe is -75°C to +100°C. However, module identity and probe materials can affect the final specified VT range for a given probe.

TEMPERATURE VS. SPINNING SPEED FOR VARIOUS MODULES
Temperature increases in a sample due to frictional heating from spinning. This data compares the amount of heating for different rotor sizes spinning at 25oC. Note the speeds are normalized to show zero to maximum spinning speed for each of the rotor sizes.VT flow rate is optimized for each rotor size (15 lpm for 1.2 mm, 25 lpm for 1.6 mm, 30 lpm for 3.2 mm, and 35 lpm for 4 mm rotor).
