I-vacuum decompression concentrators isetshenziswa kabanzi ezimbonini ezahlukahlukene ukugxilisa ingqondo nokuhlanza amasampula.Lobu buchwepheshe obusha buguqula inqubo yokukhipha izincibilikisi kumasampula, okwandisa ukusebenza kahle nokunemba.Kulesi sihloko, sizohlola ukuthi ama-vacuum concentrator asebenza kanjani kanye nokusetshenziswa kwawo emikhakheni ehlukene.
Umgomo wokusebenza we-vacuum decompression concentrator ukuhwamuka ngaphansi kwengcindezi encishisiwe.Uma isampula equkethe i-solvent ifakwa ku-concentrator, sebenzisa ipompo yokuhlanza ukuze unciphise ingcindezi.Ukunciphisa ukucindezela kwehlisa iphuzu lokubilisa le-solvent, livumele ukuba lihwamuke ekushiseni okuphansi kakhulu kunokujwayelekile.I-solvent ehwamukile ibe isifinyezwa futhi iqoqwe ngokuhlukana, kushiye isampula eligxilile.
Enye yezinzuzo ezibalulekile zokusebenzisa i-vacuum concentrator izinga lokuhwamuka okusheshayo.Ngokusebenza ngaphansi kwengcindezi encishisiwe, ama-athomu ancibilikayo anendawo eyengeziwe nenkululeko yokuhamba, okuholela ekuhwamukeni okusheshayo.Lokhu akugcini nje ukugcina isikhathi, kodwa futhi kunciphisa izindleko zokushisa namandla.Ukwengeza, ukuhwamuka kwezinga lokushisa eliphansi kuvimbela ukuwohloka kokushisa kwezinhlanganisela ezibucayi, kuqinisekisa ubuqotho besampula.
Ama-concentrators e-vacuum decompression asetshenziswa kakhulu ezimbonini ezahlukahlukene ezifana nemithi, ukudla neziphuzo, ukuqapha imvelo kanye ne-forensics.Embonini yezemithi, isetshenziswa ekutholeni izidakamizwa, ekwakhiweni nasekulawuleni ikhwalithi.Ngokususa izincibilikisi, kuvumela ukuhlukaniswa kwezithako zemithi ezisebenzayo, okuvumela ukuthuthukiswa kwezidakamizwa okuphumelelayo.Iphinde isetshenziselwe ukulungiselela isampula ocwaningweni lwe-bioanalytical ngaphandle kwezinyathelo zokuhwamuka kwe-solvent edla isikhathi.
Embonini yokudla neziphuzo, i-vacuum decompression concentrators isetshenziselwa ukugxilisa ama-flavour namaphunga.Ithuthukisa iphunga kanye nokunambitheka kokudla ngokususa ama-solvents amaningi.Ibuye isetshenziswe ekukhiqizeni amajusi, lapho idlala indima ebalulekile ekususeni amanzi kanye nokwandisa ukugxila kokunambitheka kwemvelo.
Amalabhorethri aqapha imvelo asebenzisa ama-vacuum concentrator ukuze ahlaziye i-volatile organic compounds (VOC).Lezi zinhlanganisela zingaba nomthelela omkhulu kukhwalithi yomoya, futhi ngokuvamile zenzeka ezindaweni eziphansi.Ngokusebenzisa ama-concentrator, imikhawulo yokutholwa ingehliswa, okuvumela izilinganiso ezinembe kakhudlwana.Ukwengeza, ama-concentrator asiza ukususa izingxube eziphazamisayo eziphazamisa ukuhlonza kanye nenani labahlaziyi abaqondiwe.
Kusayensi yezobunhloli, izikhonzi ze-vacuum decompression zisetshenziselwa ukukhipha nokugxilisa ubufakazi bokulandelela.Lokhu kuhlanganisa ukukhipha izidakamizwa, iziqhumane nezinye izakhi eziguquguqukayo ezivela kumatrices ahlukahlukene njengegazi, umchamo kanye nomhlabathi.Ukukhula kokuzwela nokusebenza kahle kwama-concentrator kusiza ukuthwebula ubufakazi obubalulekile ukuze kuxazululwe ubugebengu futhi kusekele uphenyo lwezomthetho.
Ukufingqa, i-vacuum concentrator iyithuluzi elinamandla lokugxilisa isampula nokuhlanza ezimbonini ezihlukahlukene.Ikhono layo lokuhwamuka ngokushesha izincibilikisi ngaphansi kwengcindezi encishisiwe liguqule ukulungiswa kwesampula.Lobu buchwepheshe busetshenziswe emikhakheni eyahlukene, kusukela kwezemithi kuya ekuqaphelweni kwemvelo kanye nokuhlolwa kwezentengiselwano.Ngokusebenza kahle okuthuthukisiwe nokunemba okuthuthukisiwe, ama-vacuum concentrator ayaqhubeka nokubamba iqhaza elibalulekile ekuthuthukiseni ucwaningo lwesayensi nezinqubo zezimboni.
