1. Kwa mpweya womwewo wa adsorbed (adsorbate) mu adsorprtion iliyonse, kutentha kwapansi, kuthamanga kwapamwamba ndi mphamvu yaikulu ya adsorbing.
2. pamene mayamwidwe amakhalabe okhazikika;mwinamwake, kutentha kwapamwamba, kuthamanga kwapansi ndi mphamvu yaing'ono ya adsorbing.Ngati kutentha sikunasinthe, desorption ndi decompression (vacuum pumping) kapena pansi pa kupanikizika kwabwinoko kumatchedwa pressure swing adsorption (PSA) pakachitika adsorption pansi pa kukanidwa.
3. Monga tawonera pamwambapa, kukula kwa adsorption ya oxygen ndi nitrogen ndi carbon molecular sieve kumasiyana kwambiri.Nayitrojeni ndi okosijeni zimatha kulekanitsidwa chifukwa cha kusiyana kwa kukula kwa mpweya ndi mpweya wa nayitrogeni kuchokera mumlengalenga movutikira.Kuthamanga kukakwera, sieve ya carbon molecular imatulutsa mpweya ndipo imapanga nayitrogeni;pamene kuthamanga kutsika, sieve imachotsa mpweya ndi kubwezeretsanso nayitrogeni.Nthawi zambiri, jenereta ya nayitrogeni ya PSA imakhala ndi ma adsorbers awiri, imodzi yomwe imatulutsa mpweya ndikutulutsa nayitrogeni, ndipo ina imawononga mpweya ndikubwezeretsanso nayitrogeni.Mwa njira iyi, nayitrogeni imapangidwa mosalekeza.
