Cov tshuaj tua kab rau Isoprocarb, suav nrog kev pom zoo, ib puag ncig txoj hmoo, eco-toxicity thiab teeb meem kev noj qab haus huv tib neeg.

Paub meej

Isoprocarb Residue Detection Test Card
Cat.KB11301K-10T

Txog
Cov khoom siv no yog qhov tsim nyog rau kev tshawb pom qhov seem ntawm isoprocarb hauv cov qauv dib tshiab.
Isoprocarb yog tus kov-thiab-tua, tshuaj tua kab sai, uas yog tshuaj tua kab mob hnyav heev.Nws yog tsuas yog siv los tswj cov qoob loo cog qoob loo, nplej cicada thiab lwm yam kab tsuag ntawm cov nplej, qee cov ntoo txiv ntoo thiab qoob loo.Toxic rau muv thiab ntses.
Kev ua haujlwm siab ua kua chromatography-tandem huab hwm coj spectrometry tau siv los txiav txim qhov seem vim yog kev xaiv siab thiab kho yooj yim.Piv nrog HPLC txoj hauv kev, peb cov khoom siv qhia tau hais tias muaj txiaj ntsig zoo txog kev nkag siab, kev txwv tsis pub, cov cuab yeej siv cuab yeej thiab lub sijhawm xav tau.

Cov qauv npaj
(1) Ua ntej kuaj, cov qauv yuav tsum tau rov qab rau hauv chav tsev kub (20-30 ℃).
Cov qauv tshiab yuav tsum tau muab tshem tawm los so cov av thiab txiav mus rau hauv daim qis dua 1cm square.
(2) Nyhav 1.00 ± 0.05g qauv rau hauv 15mL polystyrene centrifuge raj, tom qab ntawd ntxiv 8mL extract, kaw lub hau, oscillate nce thiab nqis manually rau 30s, thiab cia nws sawv ntsug rau 1min.Supernatant kua yog cov qauv yuav tsum tau kuaj.
Lus Cim: Cov qauv qauv yog hais txog kev soj ntsuam xyuas zaub mov kev nyab xeeb kev ntsuas (aqsiq tsab cai lij choj no. 15 ntawm 2019).GB2763 2019 rau siv.

Cov txiaj ntsig
Tsis zoo (-): Kab T thiab Kab C yog ob qho tib si liab, xim ntawm kab T yog tob dua lossis zoo ib yam li Kab C, qhia tias cov isoprocarb hauv cov qauv yog tsawg dua LOD ntawm cov khoom siv.
Qhov zoo (+): Kab C yog xim liab, xim ntawm kab T tsis muaj zog tshaj kab C, qhia tias isoprocarbl hauv cov qauv yog siab dua LOD ntawm cov khoom siv.
Invalid: Kab C tsis muaj xim, uas qhia tias cov strips tsis raug.Hauv qhov no, thov nyeem cov lus qhia dua, thiab rov ua qhov kev ntsuam xyuas nrog cov sawb tshiab.

Cia
Txuag cov khoom siv hauv qhov chaw qhuav ntawm 2 ~ 30 ℃ deb ntawm lub teeb.
Cov khoom siv yuav siv tau hauv 12 lub hlis.
