QuEChERS (Dhakhso, Fudud, ahaansho jaban, Wax ku ool ah, Rug iyo Badbaado ah) ayaa caalami ahaan sanadihii u dambeeyay soo saaray nooc ka mid ah farsamooyinka muunad-degdegga ah ee ugu dambeeyay ee loogu talagalay ogaanshaha wax soo saarka beeraha. Waxaa markii ugu horreysay soo saaray M Anastassisdes oo ka tirsan waaxda beeraha ee Mareykanka (2003), hubin iyo hagaajin ballaaran ka dib, habka QuEChERS ayaa si rasmi ah loo soo bandhigay. Hababka diyaarinta QuEChERS ee hadhaaga sunta cayayaanka SPE ee casriyeynta version, waxay la mid tahay saamaynta nadiifinta SPE, laakiin tallaabada ka baaraandegiddu waa mid aad u kooban, waxay leedahay sifooyinka wakhtiga badbaadinta, waxtarka sare, dhaqaalaha oo si tartiib tartiib ah loo aqbalo falanqaynta guud ee shaqaalaha. Isticmaalka xirmada QuEChERS, kaliya dhawr tillaabo oo fudud ayaa loo baahan yahay si loo dhamaystiro muunad diyaarinta falanqaynta sunta cayayaanka oo noocyo badan leh iyo kuwo badan.
BM - Sheyga taxanaha Q waa tillaabada ugu wanaagsan ee Sayniska Nolosha ee Shenzhen BM ee ku saleysan horumarinta alaabada farsamaynta degdega ah ee QuEChERS, muunado taxane ah ayaa loo isticmaali karaa in lagu ogaado haraaga sunta cayayaanka, ogaanshaha haraaga daawada xoolaha, waxyaabaha lagu daro cuntada, ogaanshaha iyo meelaha kale. Badeecada noocaan ah waxaa loo isticmaali karaa noocyo badan oo kala duwan oo adsorbent ah, sida BM - GCB depigmentation, BM - PSA si loo saaro borotiinka iyo acids organic, BM - NH2 ka saarista organic acid, BM - WCX nadiifinta walxaha alkaline, BM - C18 Ka saar dufanka iyo walxaha kale ee organic, alumina ka saar baruurta, anhydrous magnesium sulfate ka saarida qoyaanka. Intaa waxaa dheer, adigoo ku daraya qaar ka mid ah cusbada buffer, waxay kaa caawin kartaa in si fiican loo soo saaro daawooyinka.Habab kala duwan oo isku dhafan ayaa la qaadan karaa si ay ula qabsadaan baahiyaha kala duwan ee daaweynta hore. .
Taxanaha BM-Q wuxuu leeyahay:
★Heerka sare ee soo kabashada daawooyinka:heerka soo kabashada lagu qanco ee inta badan sunta cayayaanka aadka u daran.
★Codsiyada kala duwan:si loo falanqeeyo muunado kala duwan.
★Habka fududaynta:Habka waa mid fudud, tillaabooyinka qalliinka waa yar yihiin, iyo saameynta arrimaha bini'aadamka ee saxnaanta habka waa la yareyn karaa, halka waxtarka shaybaarka la wanaajin karo lana hagaajin karo socodka shaqada shaybaarka.
★Natiijooyinka waa la isku halayn karo:alaabta ceeriin ee xudunta u ah waxay ka yimaadeen alaab-qeybiye isku mid ah, iyo joogtaynta iyo xasiloonida bartilmaameedka ayaa ah kuwo la isku halleyn karo.
★Ilaalinta deegaanka ee alaabta:Isticmaalka dareeraha waa wax yar, ilaalinta deegaanka nadiifka ah, ka dib marka lagu daro dareeraha, waxay isla markiiba xiri kartaa weelka, hoos u dhigista waxyeelada hawlwadeenka.
Sharaxaada habka:
Tusaalaha habaynta:
Si loo hubiyo isku mid ahaanshaha muunada. ka hor inta aan la isticmaalin, muunado adag sida miraha iyo khudaarta waa in la gooyaa oo la isku daraa, iyo muunada khudaarta iyo miraha inta badan waa 10-15g, iyo isku-dhafka mashiinka isku-dhafka unugyada xawaaraha sare (RPM 11000). r/min-24000 r/min).
Talaabada 1: soosaar muunad:
Qadarka la qiyaasay ee muunada jabay waxay ku jirtaa tuubada soo saarista BM-Q, oo lagu daray dareerayaasha organic ku habboon tuubada soo saarista BM-Q, iyo soo saarista isku-dhafka ah ama ultrasonic ayaa loo isticmaalay si loo nadiifiyo dareeraha.
Tallaabada 2: nadiifinta
Marka loo eego shaybaarka, dooro biibiile BM-Q ah oo ku habboon tuubada nadiifinta, ka dibna ku dar soosaarka tuubada nadiifinta, si fiican u rux oo si fiican u walaaq, oo centrifuge fiirsashada dareeraha ama ogaanshaha muunada tooska ah ka dib nadiifinta tuubada nadiifka ah, matrixka kakan ayaa kara sii wad nadiifinta dareeraha nadiifinta si loo gaaro saamaynta nadiifinta ugu habboon.
Xusuusin:
Marka muunada ku biirto khadka nadiifinta, anhydrous magnesium sulfate ayaa laga yaabaa inuu yeesho qandho iyo gaas dhacdo, Soo jeedinta hirarka gariirka muddo ka dib marka la furo tuubada centrifuge waxay u leexisaa hir gariir iyo hawlo kale.
Marka biyaha ay ku jiraan xaddi badan oo biyo ah lagu daro tuubada nadiifinta ee ay ku jirto magnesium sulfate, fadlan ku dar dareeraha ka hor intaadan ku darin muunada si looga hortago natiijada ka soo baxda muunada iyo magnesium sulfate.
Fadlan fiiro gaar ah u yeelo xiritaanka badeecada. Marka badeecada la furo, waxaa lagu xiri karaa bac xiran ama lagu kaydin karaa meel qallalan ama hawo leh.
Dhibaatooyinka ka jira habka asalka ah ee QuEChERS:
Dhexdhexaadiyaha aashitada (orange), heerka soo kabashada sunta cayayaanka ee alkaline waa hooseeyaa
Xalka:
Inta lagu jiro habka falanqaynta dhexdhexaadka acidic (orange) si ay ugu biiraan soosaarka HAC iyo NaAc isku dar ah, waxay ilaalin kartaa nidaamka xalinta pH inta u dhaxaysa 4 ilaa 5, si loo xalliyo dhibaatada soo kabashada sunta cayayaanka alkaline ayaa saameynaysa.
BM-QuEChERS Macluumaadka Dalabka
Habka diyaarinta muunad A, oo ay soo jeedisay Anastassiades ee 2003, ayaa si weyn loo isticmaalo in lagu ogaado cuntada, shaybaarada biyaha deegaanka iyo ciidda wasakhaysan.The alaabta shirkadeena waxaa lagu dabaqi karaa in waaxda beeraha Shiinaha, NY / T, AOAC iyo eu EN.
