Flyash Saturation using CO2

[GTSLABS]

I am performing a CU test on Flyash and am having problems achieving B-parameter saturation. Due to the consolidation pressures I can not increase the back pressure and cell pressures further. I am reading only about 80% B value. What are the procedures for CO2 saturation? I have a tank of 25% CO2 and 75% Argon I used for welding and was wondering if that would work. Can I do this even though I have alread been using deaired water up to this point? I have also run water up thru the sample to help satuation but I am not able to achieve over 80%. Thanks in advance.
