QuEChERS (Mwachangu, Yosavuta, yotsika mtengo, Yogwira Ntchito, Yokhazikika komanso Yotetezeka) padziko lonse lapansi m'zaka zaposachedwa idapanga njira zaposachedwa zokonzekera zitsanzo zowunikira zinthu zaulimi. Idapangidwa koyamba ndi M Anastassisdes wa dipatimenti ya zaulimi ku United States (2003), ndipo pambuyo potsimikizira komanso kukonza bwino, njira ya QuEChERS idayikidwa patsogolo. QuEChERS kukonzekera njira za SPE mankhwala zotsalira kukweza Baibulo, ndi ofanana ndi SPE kuyeretsedwa kwenikweni, koma sitepe processing ndi achidule, ali ndi makhalidwe a nthawi yopulumutsa, dzuwa mkulu, chuma ndi pang'onopang'ono anavomereza ndi kusanthula ambiri ogwira ntchito. Pogwiritsa ntchito zida za QuEChERS, masitepe ochepa okha ndi omwe amafunikira kuti mutsirize kukonzekera kwachitsanzo chamagulu ambiri komanso kusanthula kwa mankhwala ophera tizilombo.

BM - Q mndandanda wa mankhwala ndi sitepe yabwino ya Shenzhen BM Life Science potengera chitukuko cha QuEChERS mofulumira processing mankhwala, mndandanda wa zitsanzo angagwiritsidwe ntchito kudziwa zotsalira mankhwala, Chowona Zanyama zotsalira mankhwala, zowonjezera chakudya, kuzindikira ndi zina. Mtundu uwu wa mankhwala angagwiritsidwe ntchito ambiri, mitundu yosiyanasiyana ya adsorbent, monga BM - GCB depigmentation, BM - PSA kuchotsa mapuloteni ndi organic zidulo, BM - NH2 kuchotsa organic acid, BM - WCX kuyeretsa zinthu zamchere, BM - C18 Chotsani mafuta ndi zinthu zina zakuthupi, aluminiyamu amachotsa mafuta, anhydrous magnesium sulfate kuchotsa chinyezi. zingathandize kuchotsa bwino mankhwala.A zosiyanasiyana collocation njira angatengere kuti agwirizane ndi zosowa zosiyanasiyana pretreatment.

BM-Q mndandanda wazinthu:
Kuchuluka kwa mankhwalawa kuchira:kuchira kokhutiritsa kwa mankhwala ambiri ophera tizilombo.
Ntchito zambiri:kusanthula zitsanzo zosiyanasiyana.
Kuphweka:njirayo ndi yosavuta, masitepe ogwirira ntchito ndi ochepa, ndipo zotsatira za zinthu zaumunthu pa kulondola kwa njirayo zikhoza kuchepetsedwa, pamene ntchito ya labotale ikhoza kukonzedwa bwino ndipo kayendetsedwe ka ntchito ka labotale kakhoza kusinthidwa.
Zotsatira zake ndi zodalirika:zida zopangira zida zimachokera kwa wothandizira yemweyo, ndipo kusasinthika ndi kukhazikika kwa chandamale kumakhala kodalirika.
Chitetezo cha chilengedwe:Kugwiritsira ntchito zosungunulira ndizochepa, kutetezedwa kwachilengedwe koyera, pambuyo powonjezera zosungunulira, kumatha kusindikiza chidebecho nthawi yomweyo, kuchepetsa kuvulaza kwa woyendetsa.

Kufotokozera za ndondomeko:

Kukonzekera kwachitsanzo:

Kuonetsetsa kufanana kwa chitsanzo.Pamaso ntchito, ndi zitsanzo olimba monga zipatso ndi ndiwo zamasamba ayenera akanadulidwa ndi homogenated, ndi chitsanzo masamba ndi zipatso zambiri 10-15g, ndi homogenation wa mkulu liwiro minofu homogenation makina (RPM 11000). r/mphindi-24000 r/mphindi).

Gawo 1: kuchotsa zitsanzo:

Kuyeza kuchuluka kwa wosweka chitsanzo ndi BM-Q m'zigawo chubu, anawonjezera abwino organic solvents kwa BM-Q m'zigawo chubu, ndi homogenizing kapena akupanga m'zigawo ntchito kuyeretsa madzi.

Gawo 2: kuyeretsedwa

Malinga ndi chitsanzo, sankhani chitoliro choyenera cha BM-Q choyeretsera, ndiyeno yonjezerani chotsitsacho ku chubu choyeretsa, gwedezani bwino ndikusakaniza bwino, ndi centrifuge ndende yamadzimadzi kapena chidziwitso chachindunji chachitsanzo. Pambuyo poyeretsa chubu choyera, masanjidwewo amatha pitirizani kuyeretsa madzi oyeretsera kuti mukwaniritse bwino kuyeretsa.

Ndemanga:

Zitsanzo zikalowa mumzere wotsuka, anhydrous magnesium sulphate akhoza kukhala ndi malungo ndi kutentha kwa mpweya, Malingaliro a vibration wave pakapita nthawi mutatha kutsegula chubu cha centrifuge chotsitsidwa ku vibration wave ndi ntchito zina.

Pamene madzi omwe ali ndi madzi ambiri akuwonjezeredwa ku chitoliro choyeretsa chokhala ndi magnesium sulphate, chonde onjezerani zosungunulira musanawonjezere chitsanzo kuti muteteze zotsatira za caking za chitsanzo ndi magnesium sulphate.

Chonde tcherani khutu ku kusindikiza kwa mankhwalawo.Chinthucho chikatsegulidwa, chikhoza kusindikizidwa mu thumba losindikizidwa kapena kusungidwa pamalo owuma kapena mpweya wabwino.

Mavuto omwe alipo munjira yoyambirira ya QuEChERS:

Pakatikati pa asidi (lalanje), kuchuluka kwa mankhwala ophera tizilombo amchere kumakhala kochepa;

Zothetsera:

M'kati kusanthula acidic sing'anga (lalanje) kuti agwirizane Tingafinye HAC ndi NaAc osakaniza, akhoza kukhala pH njira dongosolo pakati 4 mpaka 5, kuti athetse vuto la mankhwala amchere kuchira amakhudzidwa.

BM-QUEChERS Kuitanitsa Zambiri
     Njira yokonzekera chitsanzo, yopangidwa ndi Anastassiades mu 2003, yakhala ikugwiritsidwa ntchito kwambiri pofufuza chakudya, zitsanzo za madzi a zachilengedwe ndi zowonongeka za nthaka.Zogulitsa za kampani yathu zikugwiritsidwa ntchito ku dipatimenti yaulimi ya China, NY / T, AOAC ndi eu EN.
