Helium 99.999% tsarki Gas Gas

Babban tushen helium shine rijiyoyin iskar gas. Ana samun shi ta hanyar aikin liquefaction da cirewa.Saboda karancin helium a duniya, yawancin aikace-aikacen suna da tsarin farfadowa don dawo da helium.
Helium yana da mahimman aikace-aikace a cikin sashin sararin samaniya, kamar isar da iskar gas da matsi don roka da masu tallan kumbo, da kuma azaman wakili na matsa lamba don tsarin ruwa na ƙasa da na jirgin. Saboda ƙananan ƙarancinsa da yanayin kwanciyar hankali, ana amfani da helium sau da yawa don cika balloon kallon yanayi da balloon nishaɗi don samar da ɗagawa. Helium yana da aminci fiye da hydrogen mai ƙonewa saboda baya ƙonewa ko haifar da fashewa. Liquid helium na iya samar da yanayi mara ƙarancin zafin jiki don amfani da fasaha mai ƙarfi da kuma hoton maganadisu na maganadisu (MRI), yana kiyaye ƙarancin yanayin zafi mai ƙarancin ƙarfi da ake buƙata don sarrafa maganadisu.

A cikin fannin likitanci, ana amfani da helium don kula da yanayin cryogenic don superconductor a cikin na'urorin haɓakar maganadisu da ƙarin jiyya kamar tallafin numfashi. Helium yana aiki azaman iskar kariya marar aiki don hana halayen iskar shaka yayin walda kuma ana amfani dashi a cikin gano gas da fasahar gano ɗigo don tabbatar da ƙarancin kayan aiki da tsarin. A cikin binciken kimiyya da dakunan gwaje-gwaje, ana amfani da helium sau da yawa azaman iskar gas don chromatography na iskar gas, yana samar da ingantaccen yanayin gwaji. A cikin tsarin masana'antu na semiconductor, ana amfani da helium don sanyaya kuma don ƙirƙirar yanayi mai tsabta, tabbatar da kwanciyar hankali na tsarin samarwa da ingancin samfurin.
