The μDCB apparatus was tested with 238.9 mg of zeolite 13X and 180.{2|two} mg of activated carbon with single-component N2/He and CH4/He adsorption and desorption measurements.

These measurements are {both|each} {accurate|correct|precise} and precise. Multicomponent adsorption was also studied on zeolite 13X and activated carbon for CH4/N2 and CO2/CH4 mixtures. This {data|information} was compared with {ideal|perfect|best|excellent} and adsorbed {solution|answer|remedy|resolution|option} theory, extended dual-site Langmuir calculations {and the|and also the|as well as the|along with the|plus the} literature.
