Product Detail

Khoom cim npe

QuEChERS (Quick, Yooj yim, pheej yig, siv tau, Rugged thiab nyab xeeb) yog thoob ntiaj teb nyob rau hauv xyoo tas los no tau tsim ib hom kev npaj ceev ceev ceev tshaj plaws rau kev tshawb nrhiav cov khoom ua liaj ua teb. Nws yog thawj zaug tsim los ntawm M Anastassisdes ntawm Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb (2003), thiab tom qab kev txheeb xyuas thiab kev txhim kho, QuEChERS txoj kev tau ua tiav. QuEChERS kev npaj ntawm SPE tshuaj tua kab residues upgrade version, nws zoo ib yam li cov SPE purification nyhuv, tab sis cov txheej txheem yog ntau concise, muaj cov yam ntxwv ntawm lub sij hawm txuag, high efficiency, kev khwv nyiaj txiag thiab maj mam txais los ntawm cov kev soj ntsuam ntawm cov neeg ua hauj lwm. Siv cov khoom siv QuEChERS, tsuas yog ob peb kauj ruam yooj yim yuav tsum ua kom tiav cov qauv kev npaj ntawm ntau pawg thiab ntau cov tshuaj tua kab.

BM - Q series cov khoom lag luam yog cov kauj ruam zoo tshaj plaws ntawm Shenzhen BM Life Science raws li kev txhim kho ntawm QuEChERS cov khoom lag luam sai, cov qauv ntawm cov qauv tuaj yeem siv los tshawb xyuas cov tshuaj tua kab, tshuaj tua tsiaj cov khoom seem, khoom noj khoom haus, kev tshawb nrhiav thiab lwm yam. Cov khoom no tuaj yeem siv tau ntau, ntau hom adsorbent, xws li BM - GCB depigmentation, BM - PSA tshem tawm cov protein thiab cov organic acids, BM - NH2 tshem tawm cov organic acid, BM - WCX purify alkaline tshuaj, BM - C18 tshem tawm cov rog thiab lwm yam organic teeb meem, alumina tshem tawm cov rog, anhydrous magnesium sulfate tshem tawm ntawm noo noo.Ntxiv mus, los ntawm kev ntxiv qee cov ntsev tsis muaj ntsev, nws tuaj yeem pab kom zoo dua extract cov tshuaj.A ntau txoj kev sib koom ua ke tuaj yeem siv los hloov kho cov kev xav tau sib txawv. .

BM-Q series nta:
Tus nqi siab rov qab ntawm cov tshuaj:ib qho kev txaus siab rov qab los rau feem ntau ntawm cov tshuaj tua kab ntau heev.
Kev siv ntau yam:rau kev soj ntsuam ntawm ntau yam qauv.
Txheej txheem simplicity:cov txheej txheem yog yooj yim, cov kauj ruam ua haujlwm me me, thiab cov nyhuv ntawm tib neeg cov yam ntxwv ntawm qhov tseeb ntawm txoj kev tuaj yeem raug txo kom tsawg, thaum lub chaw soj nstuam ua tau zoo tuaj yeem txhim kho thiab kev ua haujlwm hauv chav kuaj tuaj yeem txhim kho.
Cov txiaj ntsig tau ntseeg tau:cov ntaub ntawv tseem ceeb yog los ntawm tib tus neeg muag khoom, thiab qhov sib xws thiab kev ruaj ntseg ntawm lub hom phiaj yog txhim khu kev qha.
Khoom tiv thaiv ib puag ncig:cov kuab tshuaj noj yog me ntsis, huv si tiv thaiv ib puag ncig, tom qab ntxiv hnyav, tuaj yeem kaw lub thawv tam sim ntawd, txo qhov kev puas tsuaj rau tus neeg teb xov tooj.

Txheej txheem piav qhia:

Qauv ua:

Txhawm rau kom muaj qhov sib xws ntawm cov qauv.Ua ntej siv, cov khoom kuaj xws li txiv hmab txiv ntoo thiab zaub yuav tsum tau txiav thiab homogenated, thiab cov qauv ntawm cov zaub thiab txiv hmab txiv ntoo feem ntau yog 10-15g, thiab homogenation ntawm cov ntaub so ntswg ceev homogenation tshuab (RPM 11000 r/min-24000 r/min).

Kauj Ruam 1: Qauv rho tawm:

Ntsuas tus nqi ntawm cov qauv tawg yog nyob rau hauv BM-Q extraction raj, ntxiv cov organic solvents haum rau BM-Q extraction raj, thiab homogenizing los yog ultrasonic extraction yog siv los ntxuav cov kua.

Kauj Ruam 2: purification

Raws li cov qauv, xaiv qhov tsim nyog BM-Q purifying yeeb nkab, thiab tom qab ntawd ntxiv cov extract rau lub raj purifying, co zoo thiab sib tov zoo, thiab centrifuge cov kua concentration los yog cov qauv ncaj qha mus kuaj. txuas ntxiv mus purify cov kua dej kom ua tiav qhov zoo tshaj plaws purifying nyhuv.

Nco tseg:

Thaum cov qauv koom nrog cov kab huv huv, anhydrous magnesium sulfate tuaj yeem ua npaws thiab cov pa tshwm sim, Cov lus qhia ntawm kev vibration nthwv dej tom qab lub sijhawm tom qab qhib lub raj centrifuge deflated rau kev vibration yoj thiab lwm yam haujlwm.

Thaum cov dej uas muaj cov dej ntau ntxiv rau hauv cov yeeb nkab purifying uas muaj magnesium sulfate, thov ntxiv cov kuab tshuaj ua ntej ntxiv cov qauv txhawm rau tiv thaiv qhov tshwm sim ntawm cov qauv thiab cov magnesium sulfate.

Thov xyuam xim rau kev sib khi ntawm cov khoom.Thaum cov khoom tsis ntim khoom, nws tuaj yeem muab ntim rau hauv lub hnab ntim khoom lossis khaws cia rau hauv qhov chaw qhuav lossis qhov cua.

Cov teeb meem uas muaj nyob rau hauv thawj QuEChERS txoj kev:

Nyob rau hauv cov kua qaub nruab nrab (txiv kab ntxwv), kuj alkaline tshuaj tua kab rov qab yog tsawg; Txawm tias nyob rau hauv nruab nrab matrix, alkaline rhiab tshuaj tua kab yog degraded.

Kev daws:

Nyob rau hauv tus txheej txheem ntawm kev soj ntsuam cov kua qaub nruab nrab (txiv kab ntxwv) mus koom nyob rau hauv lub extract HAC thiab NaAc sib tov, muaj peev xwm tswj pH daws system ntawm 4 mus rau 5, thiaj li yuav daws tau qhov teeb meem ntawm alkaline tshuaj tua kab rov qab yog cuam tshuam.

BM-QuECHERS Cov ntaub ntawv xaj
     Ib qho piv txwv kev npaj, npaj los ntawm Anastassiades nyob rau hauv 2003, tau lug siv nyob rau hauv lub nrhiav tau ntawm cov zaub mov, ib puag ncig cov qauv dej thiab av contaminants.Cov khoom ntawm peb lub tuam txhab muaj feem xyuam rau Tuam Tshoj ua liaj ua teb department, NY / T, AOAC thiab eu EN.
