I have been playing with optimizing a method for CO2 adsorption on porous carbons using our Micromeritics ASAP 2020 instrument, but can't seem to find a good balance between analysis time and data quality thus far. Specifically, I am wondering how to approach defining p0 for this analysis as the instrument cannot reach the true p0 value for CO2 @ 273 K, and what I should be looking at in terms of dosing increments. If anyone out there has the same instrument and is willing to share some parameters that work for them so I have somewhere to build off of, this would be much appreciated!

Thanks :)
