Isoprocarb Residue Detection Test Card
Za
Chida ichi ndi choyenera kudziwa bwino za isoprocarb yotsalira mu zitsanzo za nkhaka zatsopano.
Isoprocarb ndi mankhwala okhudza ndi kupha, ochita mwachangu, omwe ndi mankhwala oopsa kwambiri.Amagwiritsidwa ntchito kwambiri polimbana ndi kulima mpunga, cicada ndi tizirombo tina pa mpunga, mitengo ya zipatso ndi mbewu.Poizoni wa njuchi ndi nsomba.
High performance liquid chromatography-tandem mass spectrometry idagwiritsidwa ntchito pofuna kudziwa zotsalira chifukwa cha kusankha kwakukulu komanso chithandizo chosavuta.Ckukumana ndiMtengo wa HPLCnjira,zida zathuwonetsani zabwino zambiri zokhuza kukhudzika, malire ozindikira, zida zaukadaulo ndi nthawi yofunikira.
Zitsanzo zokonzekera
(1)Musanayesedwe, zitsanzo ziyenera kubwezeretsedwanso kutentha (20-30).℃).
Zitsanzo zatsopano zitengedwe kupukuta nthaka ndikudula zidutswa zosakwana 1cm square.
(2) Yesani 1.00± 0.05g chitsanzo mu chubu cha 15mL polystyrene centrifuge, kenaka onjezerani 8mL Tingafinye, kutseka chivindikiro, oscillate mmwamba ndi pansi pamanja kwa 30s, ndipo muyime kwa 1min.Supernatant madzi ndiye chitsanzo choti chiyesedwe.
Zindikirani: Njira yochitira zisankho ikutanthauza njira zoyendera zachitetezo cha chakudya (aqsiq decree no. 15 of 2019).GB2763 2019 kuti mumve.
Zotsatira
Zoipa(-): Mzere T ndi Mzere C zonse ndi zofiira, mtundu wa Mzere T ndi wozama kuposa kapena wofanana ndi Mzere C, kusonyeza kuti isoprocarb mu chitsanzo ndi yochepa kuposa LOD ya kit.
Zabwino(+): Mzere C ndi wofiira, mtundu wa mzere T ndi wofooka kuposa mzere C, kusonyeza isoprocarbl mu zitsanzo ndi apamwamba kuposa LOD ya zida.
Zosalondola: Mzere C ulibe mtundu, zomwe zimasonyeza kuti mizere ndi yolakwika.Pankhaniyi, chonde werenganinso malangizowo, ndikubwerezanso kuyesa ndi mzere watsopano.
Kusungirako
Sungani zida pamalo owuma a 2 ~ 30 ℃ kutali ndi kuwala.
Zidazi zitha kugwira ntchito m'miyezi 12.
