Mass of dry sample = 0.46g
Temperature
243.1 $\pm$ 0.5 $K$
Time at T
0.0 $min$
Temperature max
443.0 $K$
Time at Tmax
600.0 $min$
Comments
Sample temperature error is mostly due to possible vertical temperature gradient in the sample. Temperature reading accuracy and stability is 0.1K - Small pressure applied during sample flattening with a spatula
Type
molecular gas
Fluids
Fluid temperature
243.0 $\pm$ 5.0 $K$
Fluid pressure
0.086 $\pm$ 8.5e-04 $mbar$
Comments
P/Ps = 0.232 +/- 0.023 - Max fuid pressure = 2.52e-1 mbar (P/PS = 0.68) - Fluid temperature error depicts estimated thermal gradient of gas in the cell
