Amashanyarazi ya azote ni ibikoresho bya siyansi bitanga umusaruro wa azote ikoresheje ikoranabuhanga nka pression swing adsorption (PSA) hamwe na firigo ikora ivanze. Ibiranga harimo ubunini buke, urusaku ruke, no koroshya imikoreshereze; abakoresha bakeneye gusa guhuza isoko yingufu kugirango bahite bakora azote yuzuye, kuzamura imikorere no kugabanya ibiciro. Guhera mu 2025, amashanyarazi ya azote akoreshwa cyane mu kubika icyitegererezo cya cryogenic, magnetiki resonance (NMR), mu ifumbire mvaruganda (IVF), no mu zindi nzego, zikubiyemo inganda nk'ubuvuzi n'ubuvuzi, kurengera ibidukikije, gutunganya ibiribwa, n'ubushakashatsi mu kirere.
Amashanyarazi ya azote akoresha cyane cyane ingufu za azote zikora (PSA) azote ikomatanya hamwe na tekinoroji ya kirogenike ivanze ikora ya firigo yo gukonjesha (MRJT), cyangwa tekinoroji ya firigo ya firigo, cyangwa Pulse Tube pulse tube cryogenic firigo kugirango igere kubitandukanya na azote. Moderi zimwe, nkurukurikirane rwa LNS, zikoresha firigo ya pulse tube cryogenic firigo, bikaviramo kwangirika kwimikorere mike, mugihe moderi ya elan2 ikuramo mu buryo butaziguye no gusohora azote mu kirere.
