I-vacuum decompression concentrator ucezu lwesisetshenziswa esidlala indima ebalulekile ezimbonini ezehlukene ezifana nemithi, ukuvikelwa kwemvelo, imboni yamakhemikhali, njll. Iklanyelwe ukugxilisa izixazululo ngokususa isincibilikisi noma amanzi ngenqubo yokuhwamuka ngaphansi kwengcindezi encishisiwe. Lesi sihloko sizohlola ukubaluleka nezinzuzo zokusebenzisa i-vacuum concentrator ezinhlelweni ezahlukene.
Okokuqala, masiqonde umgomo wokusebenza we-vacuum decompression concentrator. Lesi sisetshenziswa sisebenzisa i-vacuum pump ukudala indawo enengcindezi ephansi ngaphakathi kwegumbi lokuhlushwa. Ukucindezela okuphansi kwehlisa indawo yokubilisa ye-solvent noma amanzi esixazululo, kubangele ukuthi ihwamuke ekushiseni okuphansi. Lapho i-solvent ihwamuka, isixazululo esigxilile sihlala. I-concentrator ibe isiqoqa futhi ihlukanise i-solvent ehwamukile ukuze iphinde isetshenziswe noma ilahlwe.
Imboni yezokwelapha isebenzisa ama-vacuum concentrators kakhulu ngesikhathi sokutholwa kwezidakamizwa, ukukhiqizwa kanye nezinqubo zokuzilungisa. Phakathi nenqubo yokutholwa kwezidakamizwa, abacwaningi bavame ukusebenzisa inani elikhulu lezincibilikisi ezidinga ukugxilisa ingqondo ukuhlukanisa izithako ezisebenzayo zemithi (APIs). I-vacuum encishisiwe ye-pressure concentrators ihlinzeka ngesixazululo esisebenza kahle nesingabizi sokugxilisa lezi zixazululo emazingeni okushisa ancishisiwe, ngaleyo ndlela kuncishiswe ubungozi bokucekelwa phansi kwama-API azwela ukushisa.
Ngesikhathi sokukhiqiza, abakhiqizi bemithi bavame ukudinga ukugxilisa izixazululo eziwuketshezi ukuze bathole inani elidingekayo lesidakamizwa ngaphambi kokuwagcwalisa kumafomu omthamo njengamaphilisi noma amaphilisi. Ama-vacuum concentrator asiza ukunciphisa umthamo wezixazululo, azenze zibe lula futhi zingabizi kakhulu ukuziphatha nokuthutha. Kuphinde kusize ukuthuthukisa ukusebenza kahle okuphelele kwenqubo yokukhiqiza izidakamizwa.
Embonini yokuvikela imvelo, ama-vacuum decompression concentrators angasetshenziselwa ukwelashwa kwamanzi angcolile kanye nokubuyisela i-solvent. Lezi zisetshenziswa zisiza ukususa amanzi emanzini angcolile angcolile, ukunciphisa ukukhishwa kwawo noma ukuwaphatha ngokuqhubekayo. Zibuye zisetshenziswe ezinqubweni zokubuyisela izincibilikizi, okuvumela izimboni ukuthi zikhiphe kahle futhi zisebenzise kabusha izincibilikisi ezibalulekile. Ngokusebenzisa ama-vacuum concentrator, izinkampani zinganciphisa kakhulu ukuphehlwa kukadoti futhi zinciphise umthelela wazo endaweni ezungezile.
Ngaphezu kwalokho, ama-vacuum concentrator asetshenziswa futhi kumalabhorethri amakhemikhali ukuze kugxiliswe isampula kumasu ahlukahlukene okuhlaziya. Kumakhemikhali okuhlaziya, abacwaningi bavame ukudinga ukugxilisa amasampula ukuze bakhulise ukugxilwa kwe-analyte ngezilinganiso ezinembile. Ama-vacuum concentrator ahlinzeka ngendlela esheshayo nethembekile yokususa i-solvent futhi ithole amasampula agxilile ukuze ahlaziywe okwengeziwe. Lokhu kusiza ukuthuthukisa ukuzwela nokuthembeka kwemiphumela yokuhlaziya.
Kafushane, ama-vacuum concentrators ayithuluzi elibalulekile ezimbonini ezihlukahlukene. Ikhono layo lokugxilisa ngempumelelo izixazululo kuyilapho kunciphisa ukuwohloka kokushisa kuyenza ibe yimpahla ebalulekile ekusetshenzisweni kwemithi, imvelo kanye namakhemikhali. Ngokusebenzisa lesi sisetshenziswa, izimboni zingathuthukisa izinqubo zokukhiqiza, zinciphise ukuphehlwa kukadoti futhi zithuthukise izilinganiso zokuhlaziya. Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela ukuthuthuka okwengeziwe kuma-concentrators wokuwohloka kwe-vacuum, okuvumela inqubo yokugxilisa ingqondo esebenza kahle nenembe kakhudlwana.
