GCMC problem: Extraordinarily high N2 capacity in ZIF8

[kich2018]

Dear person to whom it may concern:

As a test for GCMC simulations of RASPA2, I performed N2 adsorption simulations in ZIF-8 at 77K at varied pressures.
The results were not what I expected because the N2 adsorption amounts for given pressures ( 0.2 - 5000 Pa) were extremely high.
Cap anyone help me with this?

Best regards,

(e.g., 62

0 mol/kg at 1 Pa).
