QuEChERS (Vave, Faigofie, le taugata, Lelei, Rugged ma Safe) o loʻo faʻavaomalo i tausaga talu ai na atiaʻe ai se ituaiga o faʻataʻitaʻiga vave faʻataʻitaʻiga metotia sauniuni mo le suʻesuʻeina o mea tau faatoaga. Na muamua atiina ae e M Anastassisdes o le Matagaluega o Faatoaga a le Iunaite Setete (2003), ma ina ua maeʻa le faʻamaonia ma le faʻaleleia atili, na tuʻuina aloaia le auala QuEChERS. QuEChERS auala sauniuni o SPE toe fa'a'ato'aga fa'aleleia version, e tutusa ma le SPE fa'amamāina a'afiaga, ae o le laasaga fa'agaioiga e sili atu ona manino, o lo'o i ai uiga o le fa'asaoina o le taimi, maualuga le lelei, tamaoaiga ma faasolosolo malie ona talia e le iloiloga lautele o tagata faigaluega. I le fa'aogaina o le pusa QuEChERS, e na'o ni nai la'asaga faigofie e mana'omia e fa'amae'a ai le fa'ata'ita'iga o tapenaga ole su'esu'ega ole vaila'au fa'ato'aga e tele-vaega ma tele-toega.
BM - Q series oloa o le laasaga sili lea a Shenzhen BM Life Science e faʻavae i luga o le atinaʻeina o oloa gaosi vave QuEChERS, e mafai ona faʻaogaina se faʻasologa o faʻataʻitaʻiga i le suʻeina o mea e faʻamaʻi ai manu faalafua, suʻesuʻega faʻamaʻi vailaʻau, meaʻai faaopoopo, suʻesuʻega ma isi fanua. O lenei ituaiga o oloa e mafai ona faʻaaogaina le tele, tele o ituaiga eseese o adsorbent, e pei o le BM - GCB depigmentation, BM - PSA e aveese ai le polotini ma meaola faʻalaʻau, BM - NH2 aveesea o meaola faʻalaʻau, BM - WCX faʻamamaina mea alkaline, BM - C18 aveese ga'o ma isi mea fa'alela'au, alumina aveese ga'o, anhydrous magnesium sulfate aveesea o le susu. I le fa'aopoopoga, e ala i le fa'aopoopoina o ni masima paluga, e mafai ona fesoasoani e sili atu le fa'aaogaina o fualaau. .
BM-Q fa'asologa fa'asologa:
★Tulaga maualuga o le toe faʻaleleia o vailaʻau:ose fua faatatau toe fa'amalieina mo le tele o vaila'au fa'atosina maualuga.
★Tele ituaiga o talosaga:mo su'esu'ega o fa'ata'ita'iga eseese.
★Faigofie faiga:e faigofie le auala, o laasaga o gaioiga e laʻititi, ma o le aʻafiaga o tagata i luga o le saʻo o le metotia e mafai ona faʻaitiitia, ae mafai ona faʻaleleia le lelei o fale suʻesuʻe ma mafai ona faʻaleleia le suʻesuʻeina o galuega suʻesuʻe.
★E fa'atuatuaina i'uga:o mea autu autu e mai le kamupani lava e tasi, ma o le tumau ma le mautu o le sini e sili atu ona faatuatuaina.
★Puipuiga o le siosiomaga o oloa:e laʻititi le faʻaaogaina o le solvent, mama le puipuiga o le siosiomaga, pe a uma ona faʻaopopo le solvent, e mafai ona faʻamaufaʻailogaina le koneteina vave, faʻaitiitia le afaina i le tagata faʻapipiʻi.
Fa'amatalaga o faiga:
Fa'ata'ita'iga faiga:
Ina ia faʻamautinoa le tutusa o le faʻataʻitaʻiga. Aʻo leʻi faʻaaogaina, o faʻataʻitaʻiga mautu e pei o fualaau aina ma fualaau faisua e tatau ona tipi ma faʻafefiloi, ma o le faʻataʻitaʻiga o fualaau faisua ma fualaʻau e masani lava 10-15g, ma le homogenation o le saoasaoa o masini homogenation masini (RPM 11000). r/min-24000 r/min).
Laasaga 1: fa'ata'ita'iga fa'ata'ita'iga:
Fua fuaina o le faʻataʻitaʻiga malepelepe o loʻo i totonu o le BM-Q faʻapipiʻi faʻapipiʻi, faʻaopoopoina faʻamaʻi faʻamaʻi talafeagai i le BM-Q faʻapipiʻi faʻamau, ma faʻaaogaina le homogenizing poʻo le ultrasonic extraction e faʻamamā ai le vai.
Laasaga 2: fa'amamāina
E tusa ai ma le faʻataʻitaʻiga, filifili le paipa faʻamamā BM-Q talafeagai, ona faʻaopopo lea o le faʻaupuga i le faʻamaʻi faʻagogo, lulu lelei ma faʻafefiloi lelei, ma centrifuge le faʻaogaina o le vai poʻo le faʻataʻitaʻiga tuusaʻo. fa'aauau pea ona fa'amama le vai fa'amama e maua ai le fa'amamāina lelei.
Fa'amatalaga:
Pe a faʻatasi faʻataʻitaʻiga o laina mama, anhydrous magnesium sulfate e mafai ona i ai se fiva ma le kesi, Fautuaga o galu vibration pe a maeʻa se vaitaimi ina ua uma ona tatala le centrifuge tube deflated i galu vibration ma isi gaioiga.
Pe a faʻaopoopo le vai o loʻo i ai le tele o vai i le paipa faʻamamaina o loʻo i ai le magnesium sulfate, faʻamolemole faʻaopopo le solvent aʻo leʻi faʻaopoopoina le faʻataʻitaʻiga e puipuia ai le taunuuga o le faʻamaʻiina o le faʻataʻitaʻiga ma le magnesium sulfate.
Faʻamolemole faʻalogo lelei i le faʻamaufaʻailogaina o le oloa. Pe a faʻasalalau le oloa, e mafai ona faʻamaufaʻailogaina i totonu o le ato faʻamaufaʻailoga pe teu i totonu o se nofoaga mago pe faʻafefe.
Fa'afitauli o lo'o iai ile auala muamua QuEChERS:
I le ala oona (lanu moli), e maualalo le fua faatatau o le toe fa'aleleia o vailaau fa'alafua;
Tali:
I le faagasologa o le auiliiliina o le ala acidic (lanu moli) e auai i le vaega sii mai HAC ma NaAc paluga, e mafai ona faatumauina pH fofo faiga i le va o le 4 i le 5, ina ia foia ai le faafitauli o le toe faaleleia o vailaau faalafua alkaline ua aafia.
BM-QUECHERS Fa'amatalaga oka
O se faʻataʻitaʻiga faʻataʻitaʻiga metotia, na tuʻuina mai e Anastassiades i le 2003, ua faʻaaogaina lautele i le suʻesuʻeina o meaʻai, faʻataʻitaʻiga vai o le siosiomaga ma eleele eleelea. O oloa a la matou kamupani e faʻatatau i le matagaluega o faʻatoaga a Saina, NY / T, AOAC ma eu EN.
