Ubushuhe bwa molekile ya elegitoronike 5A ni angstroms 5, nanone bita calcium ya molekile ya calcium.Irashobora gukoreshwa mubikoresho byumuvuduko wa adsorption yinganda zikora ogisijeni ninganda zikora hydrogen。
Ihame ryimikorere ya molekile ya molekile ifitanye isano ahanini nubunini bwa pore ya sikile ya molekile, wBishobora adsorbike ya molekile ya gaze ya diameter ya molekile ntoya kuruta ubunini bwa pore.Ninini yubunini bwa pore, nubushobozi bwa adsorption.Ingano ya pore iratandukanye, kandi ibintu bishungura kandi bitandukanijwe nabyo biratandukanye.Iyo bikoreshejwe nka desiccant, icyuma cya molekile gishobora gukuramo kugeza 22% byuburemere bwacyo mubushuhe.
