I have calibrated and determined the various volume parameters like Manifold volume, Sample cell volume and void volume. I have also interfaced a pressure transducer and the various valve controls. I'm using nitrogen gas as my adsorbate and BCR 171 Alumina sample as my adsorbent. I'm finding it difficult to incorporate the real gas coefficient in my calculations to analyze the behavior of the adsorbate in the region where the sample cell is immersed in the liquid nitrogen bath. As a result I'm not able to obtain the desired isotherm curve for my sample. An example consisting of step-wise calculations would be really helpful. I am willing to share the various volume and pressure parameters that I have obtained so far. Thank you.
