Comments

Run 1 - 14.4 g of sample used. Upon application of vacuum vigorous outgassing was observed. Total degas time approximately 16 hours. Vacuum at start of analysis was 0.0012 mbar.

 

Run 2 - 15.6 g of sample used. Upon application of vacuum vigorous outgassing was observed. Total degas time approximately 21 hours. Vacuum at start of analysis was 0.0011 mbar.

 

Run 3 - 15.8 g of sample used. Upon application of vacuum vigorous outgassing was observed. After 67 hours degassing the starting vacuum was 0.0011 mbar.

 

Degas time of Run 1 is suspected to have been insufficient therefore the result is reported as the mean of Runs 2 and 3.

Conclusions:

The Vapour pressure was determined to be 2.43 Pa at 20°C.

Executive summary:
