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 ± 5.0 K
Fluid pressure
0.014 ± 1.4e-04 mbar
Comments
P/Ps = 0.0378 +/- 0.0038 - Max fuid pressure = 2.52e-1 mbar (P/PS = 0.68) - Fluid temperature error depicts estimated thermal gradient of gas in the cell
