It is very difficult to understand this experiment. There is so much left unsaid. As I understand it, the first phase loading with zero change in pressure and the second phase loading is marked when pressure begins to increase presuming that all D&H flow is being absorbed in the first phase. I also assume they determined the loading ratios by the flow rates instead of weighing the loaded samples.
Are we to assume that multiple runs were with new Pd? In other words, the six PZ runs used six PZ samples. Or were they progressive runs with two samples. <sigh> I guess you had to be there. Terry
