WebA mass spectrum will usually be presented as a vertical bar graph, in which each bar represents an ion having a specific mass-to-charge ratio (m/z) and the length of the bar indicates the relative abundance of the ion. The most intense ion is assigned an abundance of 100, and it is referred to as the base peak. WebIt is remarkable that the CO 2 mass consumption is greater at higher CO 2 ratios in the porous medium condition, while it was the opposite in the bulk condition. The rate of CO 2 gas uptake showed a smaller magnitude (by one order) and longer equilibrium time for the porous medium condition, except for the 75% of CO 2 , which support the limited CO 2 …
