I-vacuum decompression concentrators isetyenziswa ngokubanzi kumashishini ahlukeneyo ukugxila kunye nokucoca iisampulu. Ubuchwephesha obutsha buguqula inkqubo yokususa izinyibilikisi kwiisampulu, ukwandisa ukusebenza kakuhle kunye nokuchaneka. Kweli nqaku, siza kuphonononga indlela ivacuum concentrators esebenza ngayo kunye nokusetyenziswa kwazo kwiinkalo ezahlukeneyo.
Umgaqo-siseko wokusebenza we-vacuum decompression concentrator yi-evaporation phantsi koxinzelelo oluncitshisiweyo. Xa isampuli equkethe i-solvent ifakwe kwi-concentrator, sebenzisa ipompo yokucoca ukunciphisa uxinzelelo. Ukunciphisa uxinzelelo kunciphisa indawo yokubilisa ye-solvent, evumela ukuba ikhuphe kwiqondo lokushisa eliphantsi kakhulu kunesiqhelo. I-solvent e-evaporated emva koko iyancipha kwaye iqokelelwe ngokwahlukileyo, ishiya isampuli egxininisiweyo.
Olunye uncedo olubalulekileyo lokusebenzisa isigxininisi esifunxayo lisantya somphunga okhawulezayo. Ngokusebenza phantsi koxinzelelo oluncitshisiweyo, iimolekyuli ezinyibilikayo zinendawo eninzi kunye nenkululeko yokuhamba, okukhokelela ekuguqukeni komphunga ngokukhawuleza. Oku akugcini nje ukugcina ixesha, kodwa kunciphisa iindleko zokufudumeza kunye namandla. Ukongeza, ubushushu obuphantsi bobushushu buthintela ukuthotywa kwe-thermal yeekhompawundi ezibuthathaka, kuqinisekisa imfezeko yesampulu.
I-vacuum decompression concentrators isetyenziswa ngokubanzi kumashishini ahlukeneyo afana namayeza, ukutya kunye neziselo, ukubeka iliso kokusingqongileyo kunye ne-forensics. Kwishishini lamachiza, lisetyenziswa ekufumaneni amachiza, ekuqulunqweni nasekulawuleni umgangatho. Ngokususa izinyibilikisi, oko kwenza kubekelwe bucala izithako ezicocekileyo ezisebenzayo zamayeza, okwenza ukuba uphuhliso lwamachiza lusebenze. Ikwasetyenziswa kulungiselelo lwesampulu kuphando lwe-bioanalytical ngaphandle kwamanyathelo athatha ixesha lokunyuka kwe-solvent.
Kwishishini lokutya kunye nesiselo, i-vacuum decompression concentrators isetyenziselwa ukugxininiswa kweencasa kunye neziqholo. Yongeza ivumba kunye nencasa yokutya ngokususa izinyibilikisi ezigqithisileyo. Ikwasetyenziselwa ukuveliswa kweejusi, apho idlala indima ebalulekileyo ekususeni amanzi kunye nokwandisa ukuxinwa kweencasa zendalo.
Iilabhoratri zokubeka iliso kokusingqongileyo zisebenzisa i-vacuum concentrators ukuhlalutya i-volatile organic compounds (VOC). Ezi khompawundi zinokuba nempembelelo enkulu kumgangatho womoya, kwaye kaninzi zenzeka kwiindawo eziphantsi. Ngokusebenzisa i-concentrators, imida yokubona inokuthotywa, ivumela imilinganiselo echanekileyo. Ukongezelela, i-concentrators inceda ukususa ii-compounds eziphazamisayo eziphazamisa ukuchongwa kunye nobungakanani be-analytes target.
Kwinzululwazi yophando-nzulu, i-vacuum decompression concentrators isetyenziselwa ukutsalwa kunye nokuxinana kobungqina bokulandelela. Oku kubandakanya ukukhupha amachiza, iziqhushumbisi kunye nezinye iikhompawundi eziguquguqukayo ezivela kwiimatriki ezahlukeneyo ezifana negazi, umchamo kunye nomhlaba. Ukwanda kobuntununtunu kunye nokusebenza kakuhle kwezihlanganisi kunceda ekubambeni ubungqina obubalulekileyo ukusombulula ulwaphulo-mthetho nokuxhasa uphando olusemthethweni.
Ukushwankathela, i-vacuum concentrator sisixhobo esinamandla soxinzelelo lwesampulu kunye nokucocwa kumashishini ahlukeneyo. Ukukwazi kwayo ukukhupha izinyibilikisi ngokukhawuleza phantsi koxinzelelo oluncitshisiweyo kuguqule ukulungiswa kwesampulu. Le teknoloji isetyenziswe kwiinkalo ezininzi, ukusuka kumachiza ukuya ekubekweni kweliso kwendalo kunye ne-forensics. Ngokuchaneka okwandisiweyo kunye nokuchaneka okuphuculweyo, i-vacuum concentrators iyaqhubeka idlala indima ebalulekileyo ekuqhubeleni phambili uphando lwezenzululwazi kunye neenkqubo zoshishino.
