8. 60, we found that repeating the high pressure, high-temperature treatment on the purified material after each cycle increases the neon content linearly. The neon incorporation increased from 0.1% to 0.3% after four successive treatments. The neon was analyzed by first pyrolyzing the solid material at 1000 °C, which releases the neon and is detected with a quadrupole mass spectrometer.
