- UchanekoImida yokuchongwa ifikelelainqanaba le-ppt, yenzelwe iimetali ezicocekileyo kakhulu ze-semiconductor-grade (≥99.9999% ubumsulwa).
- Ixabiso: Iphezulu kakhulu (> $714,000 USD), kuphela kwiilabhoratri eziphambili.
- I-In-Situ X-ray Photoelectron Spectroscopy (XPS)
- UmgaqoIhlalutya imeko yeekhemikhali ezingaphezulu komhlaba ukuze ibone iileya ze-oxide okanye ii-phase zokungcola
- UchanekoIsisombululo sobunzulu be-nanoscale kodwa sinqunyelwe kuhlalutyo lomphezulu.
- Ixabiso: Phezulu (~$429,000 USD), kunye nokugcinwa okuntsonkothileyo.
II. Izisombululo zokuFumanisa eziCetyisiweyo
Ngokusekelwe kuhlobo lwesinyithi, umgangatho wobumsulwa, kunye nohlahlo lwabiwo-mali, kucetyiswa le midibaniso ilandelayo:

- IingeneloIgubungela ukungcola okulandelelanayo kunye nohlalutyo lwe-isotope ngokuchanekileyo okuphezulu.
- IziceloIzinto ze-semiconductor, iithagethi zokutshiza.
- IiMetali eziQinisekisiweyo eziPhakamileyo (99.9%–99.99%)
- UbuchwephesheI-ICP-OES + i-Chemical Titration 24
- Iingeneloisebenza kakuhle emaliniiyonke ~ $214,000 USD), ixhasa ukufunyanwa ngokukhawuleza kwezinto ezininzi.
- IziceloI-tin yokucoca okuphezulu kwezemveliso, ubhedu, njl.
- Izinyithi ezixabisekileyo (Au, Ag, Pt)
- UbuchwephesheUvavanyo loMlilo lwe-XRF + 68
- IingeneloUvavanyo olungatshabalalisiyo (i-XRF) oludityaniswe nokuqinisekiswa kweekhemikhali okuchaneke kakhulu; ixabiso lilonke~71,000–71,000–143,000 USD
- Izicelo: Ubucwebe, i-bullion, okanye iimeko ezifuna ukuthembeka kwesampuli.
- Izicelo Ezinobuzaza Ngeendleko
- UbuchwephesheUhlalutyo lweKhemikhali + Ukuqhuba/Ubushushu24
- IingeneloIxabiso lilonke< $29,000 USD, ifanelekile kwii-SME okanye ukuhlolwa kwangaphambili.
- IziceloUkuhlolwa kwezinto eziluhlaza okanye ulawulo lomgangatho kwindawo.
