QuEChERS (Kurumidza, Kureruka, kuve isingadhure, Kushanda, Yakakangwa uye Yakachengeteka) iri pasi rose mumakore achangopfuura yakagadzira mhando yeazvino ichangoburwa yekugadzirira sampu nzira yekuona zvigadzirwa zvekurima. Yakatanga kuvandudzwa naM Anastassisdes vebazi reUnited States rekurima (2003), uye mushure mekuongorora kwakadzama nekuvandudza, nzira yeQuEChERS yakaiswa pamberi. QuEChERS nzira dzekugadzirira dzeSPE pesticide residues upgrade version, yakafanana neSPE yekuchenesa mhedzisiro, asi danho rekugadzirisa rakapfupika, rine hunhu hwekuchengetedza nguva, kushanda kwakanyanya, hupfumi uye zvishoma nezvishoma kugamuchirwa nekuwongorora kwevashandi. Uchishandisa QuEChERS kit, matanho mashoma akareruka anodiwa kuti apedze gadziriro yemuenzaniso yemhando dzakasiyana-siyana uye yakawanda-yakasara yekuongorora mishonga yezvipembenene.

BM - Q yakatevedzana chigadzirwa inhanho yakanakisa yeShenzhen BM Hupenyu Sayenzi yakavakirwa pakuvandudzwa kweQuEChERS kukurumidza kugadzirisa zvigadzirwa, mutsara wemuenzaniso unogona kushandiswa mukuona masara emushonga wezvipembenene, kuona zvisaririra zvemishonga yemhuka, zvinowedzera zvekudya, kuona uye zvimwe minda. Rudzi urwu rwechigadzirwa runogona kushandiswa akawanda, akawanda akasiyana marudzi e adsorbent, akadai seBM - GCB depigmentation, BM - PSA kubvisa mapuroteni uye organic acids, BM - NH2 kubviswa kwe organic acid, BM - WCX kuchenesa alkaline zvinhu, BM - C18 bvisa mafuta uye mamwe maorganic matter, alumina bvisa mafuta, anhydrous magnesium sulfate kubviswa kwemwando.Mukuwedzera, nekuwedzera mamwe mabuffer salts, zvinogona kubatsira kuburitsa zvirinani mishonga.Nzira dzakasiyana-siyana dzekugovanisa dzinogona kugamuchirwa kuti dzienderane nezvinodiwa zvakasiyana-siyana zvekutanga. .

BM-Q akateedzera zvinhu:
★Mwero wepamusoro wekupora kwemishonga:chiyero chinogutsa chekupora kwezvizhinji zvezvipembenene zvakanyanya polar.
★Zvakawanda zvekushandisa:kuongororwa kwemhando dzakasiyana dzemasampuli.
★Maitiro ari nyore:iyo nzira iri nyore, matanho ekushanda maduku, uye mhedzisiro yezvikonzero zvevanhu pakururama kwenzira inogona kuderedzwa, nepo kushanda kwerabhoritari kunogona kuvandudzwa uye kufambiswa kwebasa re laboratori kunogona kuvandudzwa.
★Mibairo yacho inovimbika:iyo yakakosha zvinhu zvakasvibiswa zvinobva kumutengesi mumwe chete, uye kuwirirana uye kugadzikana kwechinangwa kunowedzera kuvimbika.
★Kudzivirirwa kwezvakatipoteredza:iyo solvent inoshandiswa idiki, yakachena kuchengetedza kwezvakatipoteredza, mushure mekuwedzera solvent, inogona kuvhara mudziyo nekukurumidza, kuderedza kukuvadza kune anoshanda.

Tsanangudzo yemaitiro:

Sample processing:

Kuti ive nechokwadi chekufanana kwemuenzaniso.Usati washandiswa, sampuli dzakasimba dzakadai semichero nemiriwo dzinofanirwa kuchekwa uye kusanganiswa, uye sampuli yemiriwo nemichero inowanzoita 10-15g, uye homogenation yehigh speed tissue homogenation machine (RPM 11000). r/min-24000 r/min).

Danho 1: muenzaniso wekutora:

Yakayerwa huwandu hwesampuni yakatyoka iri muBM-Q yekubvisa chubhu, yakawedzera yakakodzera organic solvents kuBM-Q yekubvisa chubhu, uye iyo homogenizing kana ultrasonic extraction yakashandiswa kuchenesa mvura.

Danho rechipiri: kucheneswa

Zvinoenderana nemuenzaniso, sarudza iyo yakakodzera BM-Q yekuchenesa pombi, uye wobva wawedzera iyo yakadhirowa kune yekuchenesa chubhu, zunza zvakanaka uye sanganisa zvakanaka, uye centrifuge iyo yemvura yekumisikidza kana yakananga sampuli yekuona.Mushure mekuchenesa chubhu kucheneswa, yakaoma matrix inogona. ramba uchichenesa mvura yekuchenesa kuti uwane iyo yakanaka yekuchenesa maitiro.

Notes:

Kana sampuli yajoinha yekuchenesa mutsara, anhydrous magnesium sulfate inogona kunge iine fivha uye gasi kuitika, Mazano evibration wave mushure menguva yenguva mushure mekuvhura iyo centrifuge chubhu yakaderedzwa kune vibration wave uye mamwe maoperation.

Kana iyo mvura ine yakawanda yemvura yakawedzerwa kune yekuchenesa pombi ine magnesium sulfate, ndapota wedzera iyo solvent usati wawedzera sampuli kudzivirira mhedzisiro yecaking yemuenzaniso uye magnesium sulfate.

Ndapota teererai kuiswa chisimbiso chechigadzirwa.Kana chigadzirwa chacho chisina kuvharwa, chinogona kuiswa chisimbiso muhomwe yakavharwa kana kuchengetwa munzvimbo yakaoma kana inofefetera.

Matambudziko aripo mune yekutanga QuEChERS nzira:

Muiyo acid yepakati (orenji), ine alkaline pesticide kudzoreredza mwero wakaderera;Kunyangwe mune kwayakarerekera matrix, alkaline inonzwisa zvipembenene inoderedzwa.

Mhinduro:

Mukuita kuongorora acidic medium (orenji) kuti ubatanidze mune yakatorwa HAC uye NaAc musanganiswa, inogona kuchengetedza pH solution system pakati pe4 kusvika 5, kuitira kugadzirisa dambudziko rekupora kwe alkaline pesticide.
