Sample heating

To minimized heating of conductive samples, we recommend using an Efree/lowE probe. However, a combination of frictional heating from spinning and RF heating on long pulses on both channel may cause substantial sample heating and temperature gradient across the sample even in an Efree probe. The heating may damage the sample. The heating and temperature gradient across the rotor may substantially compromise the precision of measurements and data fitting.

Probe and power limitations


Use DARR and DCP experiments to set up DCPDARR. Set up magnet field drift compensation. Choose acquisition times in the indirect dimensions for the best resolution/sensitivity compromise.


The experiments were performed with crystallized u-15N,13C-labeled-N-acetyl-valine and u-15N,13C membrane protein in hydrated lipids.
