Make it possible to measure a small amount of fluorine samples - ¹⁹F MAS probe -

　・Observe small ¹⁹F signals;
　・Reduce spinning sidebands;
　・Improve quantitative evaluation,
　　in ¹⁹F solid-state NMR spectroscopy.
 

¹⁹F MAS spectra of a grain of fluorine rubber observed using CPMAS probe (left) and ¹⁹F MAS probe (right).

¹⁹F background signals
　become 1/100.

¹⁹F MAS spectra of PCTFE observed at the spinning frequencies of 24kHz (upper) and 10kHz (lower).

Spinning sidebands
　are greatly reduced.
