A pressurizable sample chamber of known volume holds a sample with unknown porosity characteristics. The sample chamber has a known pressure (or vacuum). A flow controller preferably controls the flow of the pure gas to be adsorbeb by the sample in the sample chamber. A pressure monitor preferably monitors the pressure in the sample chamber. Once the pressure approaches a target pressure, the flow controller is closed. The pressure monitor continues to monitor the pressure until it stops changing when an equilibrium is attained. The amount of gas introduced into the system through the flow controller and the volume and final pressure of the sample chamber are used to calculate the amount of gas adsorbed. This calculation is subsequently used to determine the porosity characteristics of the sample. Some of these characteristics include, but are not limited to, pore distribution and surface area.

Une chambre d'échantillon pressurisable de volume connu contient un échantillon aux caractéristiques de porosité inconnues. On connaît la pression (ou vide) de la chambre d'échantillon. Un régulateur de débit régule de préférence le débit du gaz pur devant être adsorbé par l'échantillon dans la chambre d'échantillon. Un organe de surveillance de la pression surveille de préférence la pression de la chambre d'échantillon. Lorsque la pression approche d'une pression voulue, le régulateur de débit se ferme. L'organe de surveillance de la pression continue à surveiller la pression jusqu'à ce que celle-ci arrête de changer, lorsqu'un équilibre est atteint. La quantité de gaz introduit dans le système par le régulateur de débit, ainsi que le volume et la pression finale de la chambre d'échantillon sont utilisés pour calculer la quantité de gaz adsorbé. Ce calcul sert ultérieurement à déterminer les caractéristiques de porosité de l'échantillon. Certaines de ces caractéristiques comprennent notamment, mais pas exclusivement, la répartition des pores et leur surface.
