Comment.

Run 1:

A small amount of solid was observed at the bottom of the supplied sample. The sample was

shaken to give a consistent sample. Weight of flask + stirrer bar 38.55 gram, Weight of sample

20.03 gram. Weight of flask + sample + stirrer bar after testing 58.40 gram. Weight loss during

testing 0.18 grams, corresponds to a 0.9 % weight loss.

Run 2

Initial starting pressure 0.0018 mBar.
